[PATCH BlueZ 0/1] client: add public-broadcast advertise helper

[raghava447]

This patch adds a bluetoothctl advertise helper for BLE Audio
public broadcast profile advertising.

This series adds a semantic helper:
  public-broadcast sq
  public-broadcast hq

This matches with current commands:
  service 0x1856 0x02 0x00
  service 0x1856 0x04 0x00

[PATCH BlueZ 1/1] client: Add public-broadcast profile advertise command

[raghava447]

Add an advertise submenu command for BLE Audio public broadcast profile
advertising in bluetoothctl.

The new "public-broadcast" command reuses the existing staged AD
ServiceData field for UUID 0x1856.
It supports:
- public-broadcast sq
- public-broadcast hq
- public-broadcast

The sq and hq values map to the existing raw service-data payloads:
- sq -> 0x02 0x00
- hq -> 0x04 0x00

When called without arguments, the command reports the currently staged
public-broadcast state if the staged AD service UUID is 0x1856.
Else it reports that public broadcast is not set.
