Split bootstrapped java_features.proto to keep it from leaking out.
This can cause ODR violations in downstream users who link against both the bootstrapped proto and transitive C++ gencode of java_features.proto. Once protoc is split up, we can turn the bootstrapped proto into a real cc_proto_library target and avoid this problem altogether. PiperOrigin-RevId: 630099889
