Refreshed UX for Audio Formats Setting [Backend]
This CL modifies getSurroundSound(reported=true) to always return formats
supported by device irrespective of mode.
This also adds unit tests to verify the APIs getSurroundSound and
setSurroundFormatEnabled.
Bug:171785330
Test: atest audiopolicy_tests
Test: Tested manually
