Disambiguate release and local `config_settings` via a release flag.

This flag was added to Protobuf and submitted separately due to version skew between repos.

This attempts to fix the following error from local and release settings both matching.
```
ERROR: /workspace/_build/out/external/upb/python/dist/BUILD.bazel:251:9: Illegal ambiguous match on configurable attribute "platform" in @upb//python/dist:binary_wheel:
@upb//python/dist:linux_x86_64_local
@upb//python/dist:windows_x86_64
Multiple matches are not allowed unless one is unambiguously more specialized or they resolve to the same value. See https://bazel.build/reference/be/functions#select.
