[SurfaceFlinger] add getDisplayedContentSamplingAttributes i/f
Add interface to ISurfaceComposer that can query the
graphics.composer for querying the displayed content sampling
engine's supported attributes.
Bug: 116028618
Test: Boot
Test: ran test client against prototype, see attributes reported
Test: Ran new test './libgui_test --gtest_filter="DisplayedContentSamp*"'
Test: on hwc with and without new function hook.
