I think you can just remove base::InitOnThread now (all other implementations
other than Android are empty).

Done.

-  // Threads on linux/android may inherit their priority from the thread
-  // where they were created. This sets all new threads to the default.
-  PlatformThread::SetCurrentThreadPriority(ThreadPriority::NORMAL);
