wifi: rtw89: mcc: when MCC stop forcing to stay at GO role

MCC stop might triggered by scan, and need to force to stay at GO role
to keep TX beacon. Also, AX chips need to TX more 3 beacons to ensure
GC can receive once NoA beacon before scan when GC in courtesy mode.
BE chips no needs to TX 3 more beacon because it can TX beacon every
200TU during scan, even GC in courtesy mode can receive beacon every
600TU.
