  [MSE][GStreamer] Use mse-bytestream variant on appends
https://bugs.webkit.org/show_bug.cgi?id=251866

GStreamer Merge Request https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3867
added improved MSE support in qtdemux, fixing a buffer clipping issue. For these changes to have
effect, WebKit needs to use "variant: mse-bytestream" in the caps when supplying buffers to the
AppendPipeline.

Note that using this new variant has no negative/positive effect on GStreamer versions that still
don't include the qtdemux fix.

Reviewed by Alicia Boya Garcia.

(WebCore::AppendPipeline::AppendPipeline): Use variant: mse-bytestream for qtdemux.
