audio: HAL V7 tweaks

- rename AudioBasicConfig -> AudioConfigBase to better
  match a similar structure in audio.h;

- define AudioProfile structure for defining an I/O profile;

- use AudioProfile to replace IStream.getSupported* methods
  with a single IStream.getSupportedProfiles method;

- define AudioDevice type for convenience and clarity;

- move enums definition for AudioInputFlags and AudioOutputFlags
  into XSD. This allows parsing APM config w/o depending on
  the framework code.
