  [GStreamer][WebCodecs] Video decoder flush should not clear caps and sticky events
https://bugs.webkit.org/show_bug.cgi?id=256376

Reviewed by Xabier Rodriguez-Calvar.

The element harness now has API to flush only buffers, eg force processing of the currently queued
output buffers, without clearing input caps and sticky events. The decoder uses that API, there's no
need to explicitly re-push new caps or sticky events because the input format is not expected to
change across flushes.
