-----------
[iOS] Networking can get pinned in a MediaStreaming state if the WebContent
process is suspended with MediaStreaming active

Reviewed by Eric Carlson.
ManagedMediaSource uses a timer to ensure it releases its MediaStreaming state
after a timeout, should the
page not adequately buffer during the streaming period. If the process is
suspended while this timer is active
the timer will never fire, and networking will be pinned in the MediaStreaming
state.
Add a condition to WebProcessProxy::updateMediaStreamingActivity() which will
release the MediaStreaming state
when the WebContent process is suspended.
