Bump ccache cache key on GHA (#52711)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52711

The ccache cache is not really working. That's because we don't have a way to
properly compute the cache.

I'm adding has `hashFiles` to collect all the C++ and CMake files that are used
by ccache to fix this.
