hal: Audiosphere SA+ concurrency implementation

Audiosphere effect cannot be used along with any other SA+
effects, and needs handling for such concurrent use cases.
Remove audiosphere controls from audio extention, these controls
are now moved to audio post_proc module, where both audiosphere
and SA+ events are made available providing easy detection and
handling for concurrent use cases.
Extend audio hal's set and get parameter functionality to post_proc
module, this is required to set/get audiosphere params inside
post_proc module.
