wifi: rtw89: coex: Update priority setting for Wi-Fi is scanning

Update coexistence priority setting for Wi-Fi scanning channel, the new
setting will allow Wi-Fi do RX while Bluetooth audio is not busy. Forced
to set new TDMA policy while RF calibration request come, to make sure
the calibration can do well, and switch to normal setting while the
calibration is done. Remove the code that no longer use.
