Merge M52: "Don't resume paused media. Don't resume playing media after timeout."

As titled. We shouldn't resume paused media because there's no
reason to not wait for the user interaction. We shouldn't resume
playing media if the user has moved on to other tasks and comes
back some time later.

The idle timeout for resuming playing media is 5 seconds as chosen
by a dice roll.

BUG=617815
TEST=media suspends and resumes as expected.
