Don't GONE the unsuspended video only players

Video only players are reported to RendererWebMediaPlayerDelegate as GONE
even if they're playing. This CL would make sure we only report suspended
players as GONE. This affects the logic in MediaWebContentsDelegate that
creates the power blocker for videos.
