feat: Update AppEngine RequestLog proto to add trace_sampled field. Also add a bazel build file.

The AppEngine RequestLog proto is used in Cloud Logging for request logs coming from App Engine Standard Environment. The RequestLog proto is encoded as a google.protobuf.Any message inside the protoPayload field of the LogEntry. An updated proto and bazel build file allows client libraries to decode the Any message when reading logs from the Cloud Logging API.
