-----------
[WebGPU] SharedVideoFrameWriter::write may crash if frame is invalid
https://bugs.webkit.org/show_bug.cgi?id=268846
<radar://122399334>
Reviewed by Tadeu Zagallo.
Two issues were present, first there was a release assert on a pointer
to a RefPtr and not its value and second it is not guaranteed that
mediaIdentifier has a value when there is no sharedVideoFrame.
