refactor: bazel gapics c*

[dbolduc]

Part of the work for #14171

I used a vim recording to produce these changes. It grabs the name of the library, the service_dirs, and any deps listed after grpc_utils. It makes assumptions about the contents of the BUILD.bazel file. Any nuance in the BUILD.bazel file, would get deleted.

We have to look at the contents of every BUILD.bazel file to make sure they are without nuance. That is why I am batching these PRs in sets of ~10-15. Hopefully that is not too obnoxious.
