  Only log D3D11 annotations from the thread used to initialize the annotator.
  
  Chrome makes some ANGLE calls from multiple threads for initializing WebXR
  buffers which breaks the assumption that DebugAnnotator11 is only called from a
  single thread.  Work around this by only allowing DebugAnnotator11 to log
  annotations from the thread used to initialize it.
