Move rtc::Event to rtc_base_approved. We need an event implementation in WebRTC that allows us to specify whether it's manually reset or automatically. EventWrapper currently doesn't support it and it adds a heap allocation + vtable, so rtc::Event is the lighter of the two.
I'm also tidying rtc::Event up a bit. Removing member variable that's not needed on all platforms and moving the mutex itself up in the member list given the recent alignment scare on Mac.
