Introduced WindowProcessController/Listener (10/n)
One heavy dependence between the current AMS service and activities
is process management which is heavy affected by activities and their
current state. We introduce WindowProcessController and WindowProcessListener
objects as a structured way for the process changes in AM package to
be communicated to the WM package and WindowProcessListner for activity
changes in the WM package to the communicated back to the AM package.
The ProcessRecord object in AM will own the WindowProcessController object
and also implement the WindowProcessListener.
Test: Existing tests pass
Test: go/wm-smoke-auto
