Migrate display related methods to AIDL part 3

This migrates more display related methods from ISurfaceComposer.h to the new AIDL interface.
(1) migrate getDisplaySttas() and getDisplayState() methods
(2) add new parcelables, android.gui.DisplayState, anddroid.gui.DisplayStatInfo and other utilities.
(3) all parceables are added into libgui, instead of libui, so libui is isolated from binder serialization code,which is cleaner and avoids libbinder linking errors.
