wifi: rtw89: coex: update external control length by case

Browse Source 
Update recommend external control slot length to driver. Some of the
Wi-Fi feature has its time slot requirement can not be simply controlled
by coexistence firmware TDMA timer. For example: Wi-Fi scan/MCC etc.
In the same time, coexistence need to tell driver the recommend Bluetooth
slot length to make sure Bluetooth can still has enough time slot to
traffic.
