Audio V4: Split HAL wrapper for versioning
Both core and effect Hal now have one single point of entry.
This point of entry is their respective factories:
- DevicesFactoryHalInterface::create
- EffectsFactoryHalInterface::create
Each entry point looks for their respective services supported
version, starting from the highest (currently only 2.0) and
returning the subclass wrapping this version to the most recent audio.h
framework api.
Note that EffectBufferHalInterface were previously created from static
methods (mirror and allocate) which broke the single point of entry
requirement.
As a result, buffers have now to be created from the factory like the
other classes.
Note that the death handler also need to be its own library as it is
used by versioned code and is version independent.
