bazel: Migrate java_grpc_library to use DefaultInfo (#12148)
We here address the following obstacles in grpc-java to using Bazel's
--incompatible_disable_target_default_provider_fields flag:
```

Error: Accessing the default provider in this manner is deprecated and will be removed soon. It may be temporarily re-enabled by setting --incompatible_disable_target_default_provider_fields=false. See https://github.com/bazelbuild/bazel/issues/20183 for details.
