Currently, the transmit rate, the receive rate and signal strength of "iw
dev xxx station dump" always show an invalid value. 

This is because ath12k has no logic to handle this relevant information.

To solve this issue, ath12k parses the information passed by the firmware
and passes it to mac80211.

After that, "iw dev xxx station dump" show the correct value.
Such as:

Station 00:03:7f:12:03:03 (on wlo1)
        inactive time:  600 ms
        rx bytes:       4642228
        rx packets:     23796
        tx bytes:       933967
        tx packets:     8761
        tx retries:     66
        tx failed:      0
        beacon loss:    0
        beacon rx:      8925
        rx drop misc:   191
        signal:         -20 dBm
        beacon signal avg:      -18 dBm
        tx bitrate:     1441.1 MBit/s 80MHz EHT-MCS 13 EHT-NSS 2 EHT-GI 0
        tx duration:    0 us
        rx bitrate:     1801.4 MBit/s 80MHz EHT-MCS 11 EHT-NSS 3 EHT-GI 0
        rx duration:    0 us

Depends-on:[v6,0/3] wifi: ath12k: prepare vif and sta datastructure
Link: https://patchwork.kernel.org/project/linux-wireless/cover/20240711165511.3100433-1-quic_ramess@quicinc.com/

v7:
1.use switch statement
2.use guard(mutex)(&ah->hw_mutex)
3.use info0 = le32_to_cpu(desc->rate_stats.info0) and then use u32_get_bits() everywhere
4.replace time with time_left

v6:
1.rebase against wifi: ath12k: prepare sta data structure for MLO handling

v5:
1.use ieee80211_find_sta_by_ifaddr() to avoid using base_lock

v4:
1.rebase ath-pending-202404181533
2.change ATH12K_EHT_MCS_MAX from 13 to 15

v3:
1.change wmi_vdev_stats_event to wmi_vdev_stats_params

v2:
1.change copyright
2.change name according Naming conventions for structures

  wifi: ath12k: report station mode transmit rate
  wifi: ath12k: report station mode receive rate for IEEE 802.11be
  wifi: ath12k: report station mode signal strength
