wifi: rtw89: pause/proceed MCC for ROC and HW scan

Browse source 
During (TDMA-based) MCC (multi-channel concurrency), the below two
cases might not have a good behavior on channel usage.
* ROC (remain on channel)
* HW scan
So, we tend to separate them from MCC.

The two cases would expect to operate the channel to which they want.
However, during MCC, channels are scheduled by FW MCC state mechanism.
So, channels cannot be controlled explicitly. To avoid the two cases
from operating wrong channels with chance, we pause MCC (essentially
stop FW MCC) once the two cases are coming. And then, we proceed MCC
again (essentially restart FW MCC) once the two cases finish.
