Run buildifier to add explicit loads
They will be required in Bazel 9.

Loading from rules_cc forces us to rely on a modern version of protobuf, which in turn we need to make work via our deps macros, but that fails since we can't run protobuf's own deps macros.
@jayconrod Do you have an idea how to make this work without breaking too much? Bazel 9 won't have WORKSPACE at all, but we'll be stuck supporting it for a while.
I'm not sure I understand all the subtleties of what's happening. If protobuf becomes a mandatory dependency, we need to add its transitive dependencies to go_rules_dependencies right? I guess we can't call its deps macro because we're loading it there. We could flatten and inline the contents of that deps macro maybe.
