Log Message:
-----------
hideContentUntilPendingUpdate should not unconditionally create a process
throttler activity.

<rdar://122365213>
Reviewed by Tim Horton.
hideContentUntilPendingUpdate uses a round-trip to the WebContent process,
where the reply is
bundled into the following layer transaction. This ensures that any previous
IPC messages
from the UI process have been received, and we remain hidden until the next
layer transaction
sent after those messages.
We don't need to hold a background activity and keep the WebProcess unsuspended
during this
process, and applicationDidFinishSnapshottingAfterEnteringBackground is
explicitly trying
to suspend with the intent that the un-hiding happens on the first paint after
returning
from the background.
