Mikhail Naganov 248e950798 audio: Accept I/O handle for mix ports from the client 
The client can pass the I/O handle to the HAL as part of
the requested audio port config. The HAL can store that handle
and use it as a cookie to match the port config with other HALs
(for example, SoundTrigger).

Updated behavior of IModule.setAudioPortConfig to copy
the handle for mix ports, and pass it back with the applied
config. Enforced this behavior in VTS.

Bug: 269551518
Test: atest VtsHalAudioCoreTargetTest
