audio: add reporting of gapless playback support
Add reporting of gapless playback support via
getOffloadSupport() method which replaces isOffloadSupported().
The audio HAL implementation indicates gapless support by setting flag
AUDIO_OUTPUT_FLAG_GAPLESS_OFFLOAD on an output profile in addition to
flag AUDIO_OUTPUT_FLAG_COMPRESS_OFFLOAD.
