  [GStreamer] Fix delayed dispatch of async task post MediaPlayer destruction
https://bugs.webkit.org/show_bug.cgi?id=266715

Reviewed by Philippe Normand.

When the media player is destroyed, there can still be async tasks (from AbortableTaskQueue)
ongoing, some of them related to tracks. Those tasks should be aborted, because they depend
on objects that are no longer there.

This patch aborts all pending tasks on AbortableTaskQueue destruction and also unregisters
all pending callbacks from TrackPrivateBaseGStreamer.
