Remove direct dependency of external/skia on frameworks/native
Moves all code that needs to link with libgui or libui into
frameworks/native/hwui/utils/TestWindowContext. This allows us to
run Skia automated tests against a HWUI backend to watch for
performance or correctness regressions on Android.
BUG=23556017
TEST=After this change, we can remove libui and frameworks/native/include
from external/skia/Android.mk
