Bluetooth: Audio: Add implementation for PBP and dedicated sample apps.

Browse source 
PBP API allows sources to create a Public Broadcast Announcement.
PBP API to parse a Public Broadcast Announcement.

public_broadcast_source application starts extended advertising and
includes a Public Broadcast Announcement. The advertised broadcast
audio stream quality will cycle between high and standard quality.

public_broadcast_sink application scans for broadcast sources and
synchronizes to the first found source which defines a Public Broadcast
Announcement including a High Quality Public Broadcast Audio Stream
configuration.

Add bsim tests for Public Broadcast Profile APIs.

Add shell implementation for Public Broadcast Profile APIs.
