Clean up WindowEventDispatcher some more.

. Eliminate the implementation of LayerAnimationObserver. It seems no one expects WED to be a LAO anymore.
. Remove WindowTreeHostDelegate. This involves moving some of the functions to WTH, removing some completely, and moving the remainder to the WED public API. A little icky for now, but I plan to take a pass on cleaning up WED's public API once I get it pared down.
. window_tree_host_x11_unittest provided an implementation of WTHD that was not WED. This is not a valid situation now since various functions in WTH now call directly through to WED. Replaced this with a simple EventHandler to test that events are being dispatched.
