libaudiohal: Implement simple HIDL client
This client requires both HIDL client and server to be of the same
ABI version (e.g. 32-bit).
EffectHalHidl::process and EffectHalHidl::processReverse are stubs.
Some extra warnings are logged due to unimplemented functions
in the legacy HAL.
Bug: 30222631
Change-Id: Id074131dec6d6c4f1031695abcf3ea066e92a5af
Test: Play Music (play / EQ), YouTube, Loopback RTLT, Ok Google on N5X
