<pre>WebKit::SampleBufferDisplayLayer needs to handle GPUProcess crash
https://bugs.webkit.org/show_bug.cgi?id=228824
<rdar://problem/81564477>
Reviewed by Eric Carlson.
Source/WebCore:
Manually tested.
* platform/graphics/avfoundation/objc/MediaPlayerPrivateMediaStreamAVFObjC.mm:
(WebCore::MediaPlayerPrivateMediaStreamAVFObjC::sampleBufferDisplayLayerStatusDidChange):
Recreate a new layer if the previous one failed.
Source/WebKit:
Make WebKit::SampleBufferDisplayLayer listen to GPUProcess connection being closed.
When that happens, notify its client that it failed.
