Bootstrap command refactoring: refactor `BootstrapCommand` (step 1)

This PR is a first step towards https://rust-lang.zulipchat.com/#narrow/stream/326414-t-infra.2Fbootstrap.

It refactors `BoostrapCommand` to get it closer to a state where it is an actual command wrapper that can be routed through a central place of command execution, and also to make the distinction between printing output vs handling output programatically clearer (since now it's a mess).

The existing usages of `BootstrapCommand` are complicated primarily because of different ways of handling output. There are commands that:
1) Want to eagerly print stdout/stderr of the executed command, plus print an error message if the command fails (output mode `PrintAll`). Note that this error message attempts to print stdout/stderr of the command when `-v` is enabled, but that will always be empty, since this mode uses `.status()` and not `.output()`.
2) Want to eagerly print stdout/stderr of the executed command, but do not print any additional error message if it fails (output mode `PrintOutput`)
3) Want to capture stdout/stderr of the executed command, but print an error message if it fails (output mode `PrintFailure`). This means that the user wants to either ignore the output or handle it programatically, but that's not obvious from the name.

The difference between 1) and 2) (unless explicitly specified) is determined dynamically based on the bootstrap verbosity level.

It is very difficult for me to wrap my head around all these modes. I think that in a future PR, we should split these axes into e.g. this:
1) Do I want to handle the output programmatically or print it to the terminal? This should be a separate axis, true/false. (Note that "hiding the output" essentially just means saying that I handle it programmatically, and then I ignore the output).
2) Do I want to print a message if the command fails? Yes/No/Based on verbosity (which would be the default).

Then there is also the failure mode, but that is relatively simple to handle, the command execution will just shutdown bootstrap (either eagerly or late) when the command fails.

Note that this is just a first refactoring steps, there are a lot of other things to be done, so some things might not look "final" yet. The next steps are (not necessarily in this order):
- Remove `run` and `run_cmd` and implement everything in terms of `run_tracked` and rename `run_tracked` to `run`
- Implement the refactoring specified above (change how output modes work)
- Modify `BootstrapCmd` so that it stores `Command` instead of `&mut Command` and remove all the annoying `BootstrapCmd::from` by changing `Command::new` to `BootstrapCmd::new`
- Refactor the rest of command executions not currently using `BootstrapCmd` that can access Builder to use the correct output and failure modes. This will include passing Builder to additional places.
- Handle the most complex cases, such as output streaming. That will probably need to be handled separately.
- Refactor the rest of commands that cannot access builder (e.g. `Config::parse`) by introducing a new command context that will be passed to these places, and then stored in `Builder`. Move certain fields (such as `fail_fast`) from `Builder` to the command context.
- Handle the co-operation of `Builder`, `Build`, `Config` and command context. There are some fields and logic used during command execution that are distributed amongst `Builder/Build/Config`, so it will require some refactoring to make it work if the execution will happen on a separate place (in the command context).
- Refactor logging of commands, so that it is either logged to a file or printed in a nice hierarchical way that cooperates with the `Step` debug hierarchical output.
- Implement profiling of commands (add command durations to the command log, print a log of slowest commands and their execution counts at the end of bootstrap execution, perhaps store command executions to `metrics.json`).
- Implement caching of commands.
- Implement testing of commands through snapshot tests/mocking.

Bootstrap command refactoring: consolidate output modes (step 3)

This PR is a continuation to rust-lang#126731. It consolidates the output modes of bootstrap (`Print` vs `CaptureAll` vs `CaptureStdout`) and simplifies the logic around error printing (now a command error is always printed if the failure is not ignored). It also ports even more usages of `Command` to `BootstrapCommand`, most notably the git helpers and many usages of the `output` function.

The last commit was added because the third commit made two variants of the `Tool` enum unused (no idea why, but it seems to have been a false positive that they were used before).

It can be reviewed now, but I would wait with merging until at least a few days after rust-lang#126731, just to catch any potential issues from that PR before we move further.

As a next step, I want to clean up the API of the command a little bit to make usage easier (currently it's a bit verbose), and then continue with the rest of the tasks from the tracking issue.
