The main branch hasn't supported IPC3 for tgl for a long time.

Follow-up to commit a17c282 ("xtensa-build-zephyr: remove ipc
option")

(cherry picked from commit 79e5080)

Rename:
- tgl-cavs.toml   to tgl.toml
- tgl-h-cavs.toml to tgl-h.toml

Remove the IPC3/IPC4 switch added by commit 6f71808
("xtensa-build-zephyr.py: add ipc4 build support for tgl")

This brings back consistency which is required for the .toml
split (thesofproject#8490)

The default firmware file path is standardized among vendors as follows:
IPC3
    /lib/firmware/VENDOR/sof/
    ├── community
    │   └── sof-PLAT.ri
    ├── dbgkey
    │   └── sof-PLAT.ri
    └── sof-PLAT.ri
IPC4
    /lib/firmware/VENDOR/sof-ipc4/
    └── PLAT
        ├── community
        │   └── sof-PLAT.ri
        ├── dbgkey
        │   └── sof-PLAT.ri
        └── sof-PLAT.ri\n

Currently the binaries created by the build can only be used for direct
deployment on IPC3 platforms but if one builds different vendor firmwares
the files have to be manually picked and sorted out.
We have two flags: --fw-naming and --use-platform-subdir which can be
played with but still not going to produce deployable build.

Introduce a new flag: --deployable-build
With the flag specified all other modificators are going to be ignored and
the build will do the 'right thing' to create a directory structure which
can be deployed as it is to the target's firmware directory.

To achieve this several changes needed:
PlatformConfig:
- drop the name member and replace it with a vendor string
- add a flag to indicate IPC4 platforms
  Later a new option can be added if needed for platforms which can be
  IPC3 or IPC4

Ignore fw-naming and use-platform-subdir in case of deployable build. The
options will be reset to their default in case they are changed.

symlink_or_copy extended to handle relative symlinks when the target and
link is not under the same directory.

The --deployable-build is disabled by default, it has to be enabled to
create deployable build for now.

Not sure why I thought it would be complicated; I should have done this
much sooner.
