wifi: ath12k: Refactor the format of peer rate table information

Currently, peer rate table information involves complex computation for
the rate index to update the rate table. To simplify this process, avoid
the rate index calculation by defining the rate table with bandwidth, GI,
NSS, MCS. Therefore, update the rate information based on the bandwidth,
GI, NSS and MCS information from the TLV data of monitor status Rx path.
