libaudiohal: Optimize loading for minor version upgrades

Make libaudiohal@7.1 to contain clients for core HAL
V7.1 and effect HAL V7.0. This is to avoid loading
both libaudiohal@7.1 (for core) and libaudiohal@7.0
(for effects).

Update the loader to figure out maximum minor version
and only load the library for that version.

Implemented proper conversion for the Result type
from the a.h.audio.effect library.
