This patch adds necessary structures and prepares for implementing data flow for audio I/O. Also in this patch we clarify the relationship between audio patches and buffer size for audio I/O, and between buffer size and latency. Bug: 205884982 Bug: 233816848 Test: atest VtsHalAudioCoreTargetTest Change-Id: I8522632607d4cf50a112225c19b5dd5ad8848591
