Awake physics bodies should probably be global

Or at least this might be me just projecting and hating the amount of map change bugs that have popped up.

I think make it a component instead rather than tracking it on sharedphysicsmapcomponents.

Plus when building islands you just iterate through contacts and build them then solve globally. This also has the advantage of making the lone island faster with multi-map as it's no longer per map.
