  [GStreamer] Try to detect and recover inconsistent playing state
https://bugs.webkit.org/show_bug.cgi?id=252310

Reviewed by Philippe Normand.

A series of buffer flushings could leave pipeline in an inconsistent state: top-level bin in playing with sinks in
paused. This happens if flush is triggered in the middle of paused-to-playing transition which was started by gst bin
async handling of ASYNC_DONE message.
