Use WindowInfosListener instead of SF reporting to IF
1. Moved ISetInputWindowsListener and renamed to
IWindowInfosReportedListener to be more generic
2. Updated SurfaceFlinger so it reports window infos changed instead of
directly reporting window info to InputManager
Test: Existing tests pass
Test: WindowInfosListenerTest
