[Remoting Android] Fix thread issue with OpenGL drawable

This CL has these changes:
* Store drawable's weak_ptr in ctor rather than using thread checker
  to check the thread safety of GetWeakPtr() since GetWeakPtr() is called
  in multiple threads.
* Avoid all attempts in CreateGlRendererWithDesktop() to dereference
  any weak pointer since CreateGlRendererWithDesktop() is supposed to be
  called on any thread.
* DCHECK the thread in AddDrawable(). AddDrawable is never safe to be called
  on a different thread once GlRenderer gets any side effect.
