feat: commit hash

[unlogisch04]

Change

This pull request adds the Git commit hash in the built firmware.

Notes:

The web flasher needs a new implementation, this should not be merged without the change.

⚠️ Needs testing ⚠️

[ButterscotchV]

Added this branch to my site (https://slimevr-firmware.bscotch.ca/) as unlogisch04/feat_commitid to be used for testing.

I can confirm this breaks on the web firmware tool. Check the attached log for more info:
firmware-tool-log.log

This shouldn't crash if not in a git repo (ex. downloading a release zip, etc), even though it's not much of an expected case, it's good to keep it working anyways. Maybe a big warning instead?

For firmware tool compatability, support should be added for reading the commit ID from an environment variable, as we have the metadata but no way to pass it in.

[unlogisch04]

Oh i did forgot, that it can be out of a git repo.
Thanks for testing.

@ButterscotchV could you check again? I've added error handling to the script

[ButterscotchV]

Tested again, doesn't compile

File "scripts/get_git_commit.py", line 22
    print(f"'-DGIT_REV=\"{revision}\"'")
                                      ^
SyntaxError: invalid syntax

That could be from an old version of python, f-strings are supported from python 3.6. Working fine with ubuntu and PlatformIO installed last month

Tested with these two patches with and without git repo

[ButterscotchV]

Oh also I've tested and it does appear to compile. I've added support for the GIT_REV environment variable on my web firmware tool fork, so that can also be tested hopefully (I hope I did it right -w-).

[ButterscotchV]

Works on web firmware tool perfectly 👍
