wifi: rtw89: 8922a: download template probe requests for 6 GHz band

8922a FW supports RNR parsing, provide template probe requests and
let FW do the replacement for SSID/BSSID/short SSIDs.
Don't declare WIPHY_FLAG_SPLIT_SCAN_6GHZ so proper IEs such as
6 GHz capabilities can be passed down within the same scan request.
