  [MSE][GStreamer] always reset appsink/parser state when recycling the track
https://bugs.webkit.org/show_bug.cgi?id=263532

Reviewed by Alicia Boya Garcia.

After applying [1], appsink can receive EOS event that was sent by
qtdemux before removing an "old" streamd. This marks the sink as
"received_eos" and makes it reject any events from subsequent
appends. Resulting in append failing with ParsingFailed error.
