This starts failing since rust-lang/rust#131188

### What does this PR try to resolve?

Fixes #14735

rust-lang/rust#131188 removes libstd.so from
sysroot so `cargo test -Zbuild-std` no longer links to it. That results
in a "Library not loaded: @rpath/libstd-[HASH].dylib" when testing a
proc macro.

This is a pretty niche use case, though it can be easily reproduced by
running `cargo test -Zbuild-std` in any proc-macro package. Like in
[serde-rs/serde](https://github.com/serde-rs/serde/tree/b9dbfcb4ac3b7a663d9efc6eb1387c62302a6fb4)
running it would fail.

This patch adds a special case that if it is `cargo run/test` against a
proc-macro, fill in std dynamic library search path for it.

### How should we test and review this PR?

```
CARGO_RUN_BUILD_STD_TESTS=1 cargo +nightly t --test build-std test_proc_macro
```

or

```
git clone https://github.com/serde-rs/serde
cd serde
git switch -d b9dbfcb4ac3b7a663d9efc6eb1387c62302a6fb4
cargo +nightly t --test build-std
```

Cargo
-----
- [Introduced a new `CARGO_MANIFEST_PATH` environment variable,
  similar to `CARGO_MANIFEST_DIR` but pointing directly to the manifest
  file.]
  (rust-lang/cargo#14404)
- [Added `package.autolib` to the manifest, allowing `[lib]`
  auto-discovery to be disabled.]
  (rust-lang/cargo#14591)
- [Declare support level for each crate in Cargo's Charter / crate docs.]
  (rust-lang/cargo#14600)
- [Declare new Intentional Artifacts as 'small' changes.]
  (rust-lang/cargo#14599)

Rustdoc
-------

- [The sidebar / hamburger menu table of contents now includes the
  `# headers` from the main item's doc comment]
  (rust-lang/rust#120736). This is similar
  to a third-party feature provided by the rustdoc-search-enhancements
  browser extension.

Compatibility Notes
-------------------
- [Warn against function pointers using unsupported ABI strings.]
  (rust-lang/rust#128784)
- [Check well-formedness of the source type's signature in fn
  pointer casts.]
  (rust-lang/rust#129021) This partly closes
  a soundness hole that comes when casting a function item to
  function pointer
- [Use equality instead of subtyping when resolving type dependent paths.]
  (rust-lang/rust#129073)
- Linking on macOS now correctly includes Rust's default deployment
  target. Due to a linker bug, you might have to pass
  `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to
  point to the correct frameworks. See
  <rust-lang/rust#129369>.
- [Rust will now correctly raise an error for `repr(Rust)` written
  on non-`struct`/`enum`/`union` items, since it previous did not
  have any effect.]
  (rust-lang/rust#129422)
- The future incompatibility lint `deprecated_cfg_attr_crate_type_name`
  [has been made into a hard error]
  (rust-lang/rust#129670). It was used to
  deny usage of `#![crate_type]` and `#![crate_name]` attributes in
  `#![cfg_attr]`, which required a hack in the compiler to be able
  to change the used crate type and crate name after cfg expansion.
  Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type
  = "...")]` and `--crate-name` instead of `#![cfg_attr(...,
  crate_name = "...")]` when running `rustc`/`cargo rustc` on the
  command line.  Use of those two attributes outside of `#![cfg_attr]`
  continue to be fully supported.

- Until now, paths into the sysroot were always prefixed with
  `/rustc/$hash` in diagnostics, codegen, backtrace, e.g.
    ```
    thread 'main' panicked at 'hello world', map-panic.rs:2:50
    stack backtrace:
       0: std::panicking::begin_panic
                 at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12
       1: map_panic::main::{{closure}}

       2: core::option::Option<T>::map

    note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
    ```
  [RFC 3127 said]
  (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)
  > We want to change this behaviour such that, when `rust-src`
    source files can be discovered, the virtual path is discarded
    and therefore the local path will be embedded, unless there is
    a `--remap-path-prefix` that causes this local path to be remapped
    in the usual way.

    [#129687](rust-lang/rust#129687)
    implements this behaviour, when `rust-src` is present at compile
    time, `rustc` replaces `/rustc/$hash` with a real path into
    the local `rust-src` component with best effort.  To sanitize
    this, users must explicitly supply `--remap-path-prefix=<path
    to rust-src>=foo` or not have the `rust-src` component installed.
- The allow-by-default `missing_docs` lint used to disable itself
  when invoked through `rustc --test`/`cargo test`, resulting in
  `#[expect(missing_docs)]` emitting false positives due to the
  expectation being wrongly unfulfilled. This behavior [has now been
  removed]
  (rust-lang/rust#130025), which allows
  `#[expect(missing_docs)]` to be fulfilled in all scenarios, but

<a id="1.83.0-Cargo"></a>

## Cargo

-   [Introduced a new `CARGO_MANIFEST_PATH` environment variable, similar to `CARGO_MANIFEST_DIR` but pointing directly to the manifest file.](rust-lang/cargo#14404)
-   [Added `package.autolib` to the manifest, allowing `[lib]` auto-discovery to be disabled.](rust-lang/cargo#14591)
-   [Declare support level for each crate in Cargo's Charter / crate docs.](rust-lang/cargo#14600)
-   [Declare new Intentional Artifacts as 'small' changes.](rust-lang/cargo#14599)

<a id="1.83-Rustdoc"></a>

## Rustdoc

-   [The sidebar / hamburger menu table of contents now includes the `# headers` from the main item's doc comment](rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.

<a id="1.83.0-Compatibility-Notes"></a>

## Compatibility Notes

-   [Warn against function pointers using unsupported ABI strings.](rust-lang/rust#128784)
-   [Check well-formedness of the source type's signature in fn pointer casts.](rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer
-   [Use equality instead of subtyping when resolving type dependent paths.](rust-lang/rust#129073)
-   Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to point to the correct frameworks. See [#&#8203;129369](rust-lang/rust#129369).
-   [Rust will now correctly raise an error for `repr(Rust)` written on non-`struct`/`enum`/`union` items, since it previous did not have any effect.](rust-lang/rust#129422)
-   The future incompatibility lint `deprecated_cfg_attr_crate_type_name` [has been made into a hard error](rust-lang/rust#129670). It was used to deny usage of `#![crate_type]` and `#![crate_name]` attributes in `#![cfg_attr]`, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion.
    Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type = "...")]` and `--crate-name` instead of `#![cfg_attr(..., crate_name = "...")]` when running `rustc`/`cargo rustc` on the command line.
    Use of those two attributes outside of `#![cfg_attr]` continue to be fully supported.
-   Until now, paths into the sysroot were always prefixed with `/rustc/$hash` in diagnostics, codegen, backtrace, e.g.

        thread 'main' panicked at 'hello world', map-panic.rs:2:50
        stack backtrace:

        note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

    [RFC 3127 said](https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)

    > We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way.

    [#&#8203;129687](rust-lang/rust#129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort.
    To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed.
-   The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed](rust-lang/rust#130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test](https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests.

-   [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a `dyn Trait`'s associated types that occur due to supertraits.](rust-lang/rust#130367)
-   [Update the minimum external LLVM version to 18.](rust-lang/rust#130487)
-   [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia` respectively.](rust-lang/rust#130657)
-   [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.](rust-lang/rust#130897)
-   [Visual Studio 2013 is no longer supported for MSVC targets.](rust-lang/rust#131070)
-   [The sysroot no longer contains the `std` dynamic library in its top-level `lib/` dir.](rust-lang/rust#131188)
