  [GStreamer][DMABuf] DRM modifiers handling
https://bugs.webkit.org/show_bug.cgi?id=262838

Reviewed by Xabier Rodriguez-Calvar.

In the upcoming GStreamer 1.24 release the video decoders can expose DRM modifiers during caps
negotiation. So in this build configuration (new API required) we can passthrough those modifiers to
the TextureMapper.
