MediaStream canvas.captureStream() playback to LocalSampleBufferDisplayLayer is flaky

Sometimes the system is not creating the AVSampleBufferDisplayLayer because the samples arrive 
before the media player determines whether accelerated rendering is possible.

The callbacks that update HTMLMediaElement::m_cachedSupportsAcceleratedRendering are run asynchronously and too late.
