Unifies constants accross hearing aid related profiles (2/2)

Hearing aid constants defined differently across different hearing aid
related profiles. For hearing aid device mode, HearingAidProfile and
HapClientProfile have different values for mode definition and there is also
a new BANDED hearing aid type in HapClientProfile spec. For hearing aid
device side, HearingAidProfile has only 2 kinds of side which is left
and right whereas BLE hearing aid can retrieve 27 different kinds of
audio location.

We therefore introduce a new class HearingAidInfo for mapping these
different constants across these profiles into a single unified set of
constants.
