audio: Create libraries for data types in core and effect
Add 'CoreUtils' library similar to 'HidlUtils' for the types
specific to the core HAL. Add 'EffectUtils' library similar to
'HidlUtils' for the types specific to the effects HAL. Move into
them and de-duplicate code previously scattered across the
default HAL implementation and libaudiohal. Add unit tests.
Removed 'AUDIO_{INPUT|OUTPUT}_FLAG_NONE' from the list of
values in the XSD file to avoid additional complexity due to
equivalence of this value to an empty list of flags.
