hardware_legacy: provide HAL helpers for legacy audio users

This doesn't actually create a HAL, but rather a set of helper static
libraries that device specific libraries (i.e. the old libaudio pieces)
can link against to create a proper audio HAL module.

We provide an audio_policy static wrapper and audio hardware interface
static wrapper.
