Cancel plugin channel requests when the renderer goes away.

Logic:
- Profile shutdown kills all renderer processes
- When the RMF detects the channel closing, it kills off any plugin channel requests from:
	* PluginService (which needs to check the PluginServiceFilter on the FILE thread)
	* PluginProcessHost (which may need to wait for the channel to get established)
- RMF uses the new OnPluginProcessHostFound() to cancel at the PluginService or PluginProcessHost

BUG=94704
TEST=New PluginService test, no known manual test
