  [GStreamer][WebCodecs] Prevent usage of vavp9alphadecodebin
https://bugs.webkit.org/show_bug.cgi?id=287769

Reviewed by Xabier Rodriguez-Calvar.

This decoder is not usable for WebCodecs. In the registry scanner filtering had to be moved to the
findCompatibleFactories function because otherwise the vavp9alphadecodebin, which has the Hardware
classifier, would still be selected in the shouldCheckHardwareClassifier ==
CheckHardwareClassifier::Yes path.
