Spatializer: control audio HAL latency mode

Add support of HAL stream latency mode control to Spatializer
effect controller.
- Query supported latency modes when attached to a new output stream
and register a callback to be notified of changes
- Only use a head tracker sensor if the HAL stream supports low
  latency or does not support latency mode control.
- Set the requested latency mode according to head tracking state.
