wifi: ath12k: Add support TX hardware queue stats

Browse Source 
Add support to request and receive TX hardware queue stats using
HTT stats type 3. This stats type reports MPDU mac id and hardware
queue information, including xretry, BAR, RTS, CTS, self, and QoS-null
counts, along with underrun, flush, and filter counters.

Sample output:
-------------
echo 3 >/sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats_type
cat /sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats

HTT_TX_HWQ_STATS_CMN_TLV:
mac_id = 0
hwq_id = 0
xretry = 0
underrun_cnt = 0
flush_cnt = 0
filt_cnt = 0
null_mpdu_bmap = 0
user_ack_failure = 379
ack_tlv_proc = 0
sched_id_proc = 0
null_mpdu_tx_count = 0
mpdu_bmap_not_recvd = 0
num_bar = 0
rts = 0
cts2self = 0
qos_null = 0
mpdu_tried_cnt = 379
mpdu_queued_cnt = 379
mpdu_ack_fail_cnt = 0
mpdu_filt_cnt = 0
false_mpdu_ack_count = 0
txq_timeout = 0
