wifi: ath12k: Add EHT MCS support in Extended Rx statistics

Currently, EHT MCS information is not populated. Therefore, add the EHT
MCS counter array to the peer rate statistics and update the EHT MCS
statistics from the status TLV data in the monitor Rx path. In the future,
this information will be used in the peer extended Rx statistics dump.
