[rdk-b][mt7986][wifi-hal][Add set and get BeaconRate]

[Description]
Add set and get BeaconRate wifi hal function.
The setApBeaconRate have specific input string format defined by documentation.
The unit in RDKB is Mbps, but the unit in hostapd is 100 kbps.
So, we should multiply 10 in set funtion and divide 10 in get funtion to convert the unit.
