As audio device type can not be used as bit mask any more, refactoring audio device type usages in conversion from/to HAL. Use a set of audio device types instead of bit mask. Bug: 135621476 Test: atest VtsHalAudioV5_0TargetTest Change-Id: I1a0f574744f855bb1684cd28613571399781abbc Merged-In: I1a0f574744f855bb1684cd28613571399781abbc
