RE: Dynamic modification advertising public address

Hi,

To supplement my requirements:

1. Multiple broadcast IDs are needed, e.g., ID1 ID2

2. ID1 needs to be a public address that can be dynamically modified.

3. ID2 needs to be a random address that can be dynamically modified.

Add my testing project. Test process：

1. Execute `west flash --recover` to flash the application. The actual broadcast address is "01, 0x02, 0x03, 0x04, 0x05, 0x07", and the address type is public.

2. The Android phone initiates a bond request via the NRF Connect tool. The development board accepts by pressing button 0, and the pairing is successful.

3. Modify the address set in `bt_ctlr_set_public_addr` to "01, 0x02, 0x03, 0x04, 0x05, 0x06", and compile and execute `west flash`.

4. It can be seen that the actual broadcast address has been set successfully, but the ID0 address in `SETTING` is still "01, 0x02, 0x03, 0x04, 0x05, 0x07".

5. The phone reconnects and initiates a bond request, but it fails.
