Reviewed by Ben Nham.

Make sure IPC queue from NetworkProcess to WebProcess doesn't grow too large
because the remote WebProcess is suspended.

If the queue grows too large (1024 messages), the network process will now IPC
the UIProcess, asking it to temporarily (3 seconds) wake up the remote Web
process, so we can drain the IPC queue.

This is a follow-up to 263570 at main.
