bap: add Location parameter to SelectProperties

Add relevant PACS Location field as a parameter to SelectProperties.

SelectProperties may set Audio_Channel_Allocation, which shall be chosen
from the bits set in Sink/Source Audio Locations (BAP v1.0.1 Sec. 4.4.1,
Sec 4.4.2). Hence, audio server needs to know the supported values,
which it previously could not.
