Not sure how these got missed when moving other things to `uv`, but this should clean them up. The bump to Python 3.12 is so that we can use `@override` with the simple import from `typing`. This is needed by the newest versions of `ty` to do type checking. Added the relevant `@override` annotations. Assisted-by: Antigravity with Gemini

"""Detects and prevents dependencies on LLVM's googletest.
|
|
|
|
Carbon uses googletest directly, and it's a significantly more recent version
|
|
than is provided by LLVM. Using both versions in the same binary leads to
|
|
problems, so this detects dependencies.
|
|
|
|
We also have some dependency checking at //bazel/check_deps. This is a separate
|
|
script because check_deps relies on being able to validate specific binaries
|
|
which change infrequently, whereas this effectively monitors all cc_test rules,
|
|
the set of which is expected to be altered more often.
