[Build] Updated bzlmod again (grpc#38675)

A few changes to address comments from bazelbuild/bazel-central-registry#3671

- Reintroduced a few more dependencies in the gRPC Bazel modules since those turned out to be required for some public gRPC targets (e.g. `googletest` is needed for `grpc++_test`)
- Removed `google_cloud_cpp` from the dependency as it's not yet registered to BCR and using it sometimes causes strange problems.
- Added a few public Bazel targets to `bazel_build_with_bzlmod_linux.sh` to make sure those are actually buildable.

Following-up of grpc#38626

Closes grpc#38675
