internal/fileinit: make fileinit responsible for registering concrete options types

Changes:
* Remove protoreflect.OptionsMessage and use protoreflect.ProtoMessage
now that the generated options natively implement reflection.
* Make registration of concrete option types the responsibility of
internal/fileinit since the init logic of descriptor.pb.go uses that.
* Remove equivalent logic in protoc-gen-go to special-case descriptor.
