wifi: rtw89: coex: Add coexistence policy to decrease WiFi packet CRC-ERR 

The 2 Bluetooth profiles (Hands free profile & Human interface device)
have high duty transmission, it will affect the traffic of WiFi packet
frequently. And once the WiFi traffic down to B/G mode, it will need
a better success rate to recover the transmission rate. Add new policy
option to solve the above situation.
