[iOS] Pausing a media element should discard buffered data immediately if under memory pressure.
<https://webkit.org/b/146410>
<rdar://problem/20366883>
Reviewed by Darin Adler.
When moving a media element into paused state, call purgeBufferedDataIfPossible()
right away if the system is under memory pressure.
This ensures that mediaserverd drops its forward-looking frame queue right
away instead of waiting for a new pressure notification.
