Reviewed by Jer Noble.

The optimization at the top of MediaElementSession::updateMediaUsageIfChanged
does not take into account media elements that have no currentSrc but do
have a srcObject. Don't exit early for such elements.

Store an additional bit of information on MediaSessionInfo to represent whether
the element has any source (currentSrc or srcObject).
