Summary [MSE][GStreamer] Make fake preroll asynchronous

With the current implementation the whole seek flow as executed in a single main loop cycle. As a result, the JS app had no chance to spot that video.seeking attribute is ever set to true. Also some apps listen to video.onseeking and expects that video.seeking attribute to be true in such case. That wasn't a valid assumption. Also, the behaviour isn't the same in <video> elements that are audio-only as in <audio> elements.

This happens on the Amlogic platform, that doesn't have asynchronous state changes on its audio sink. Spotify is broken there because of this problem.
