Take out MediaPlayback UI assertion when any WebProcess is playing audible media
https://bugs.webkit.org/show_bug.cgi?id=197798

Reviewed by Chris Dumez.

To keep the system from suspending the UIProcess (and all the other constellation of processes that
are necessary to play media), take a UIProcess assertion with the MediaPlayback reason whenever there
is a WebContent process that is playing audible media.
