Add interfaces to query aaudio hardware information. The new interfaces are supposed to replace the system properties. The information includes aaudio mixer burst count and aaudio hardware burst minimum usec. Bug: 193275465 Test: atest VtsHalAudioCoreTargetTest Change-Id: Id3442dae15937baba84f053f2e244bc294f4d718
