<pre>[MSE][Mac] Uncaught exception when deallocating AVSampleBufferDisplayLayer
https://bugs.webkit.org/show_bug.cgi?id=134281
Reviewed by Brent Fulgham.
AVSampleBufferDisplayLayer is throwing an exception from its -dealloc method because KVO observers exist
at the time of dealloc. Remove the observer for outputObscuredDueToInsufficientExternalProtection inside
-stopObservingLayer.
