Propagate window focus changes to plugins on the Mac

This gives plugins mostly correct window activation information; there are still a few loose ends like initial focus state and changes that happen while plugins are in background tabs, but those will be handled in follow-up bugs.

BUG=31847
TEST=Plugins that are in background windows should act accordingly (e.g., Silverlight hover effects shouldn't trigger)
