[BlueZ,05/10] shared/bap: Append bcast sink pacs to Sink PAC char

Commit Message

It is mandatory for a BAP Broadcast Sink to support the PACS Server role.
The Sink PAC characteristic should contain PAC records that expose
supported audio capabilities for receiving both unicast and broadcast
streams.

A BAP Broadcast Assistant acting as a GATT Client needs to discover the
Sink PAC characteristic on the BAP Scan Delegator peer (BAP Broadcast
Sink), in order to discover supported capabilities for receiving streams.

This commit updates the callback for handling read requests for the Sink
PAC characteristic, to also append Broadcast Sink pac structures to the
read response.
