wifi: ath12k: Support Self-Generated Transmit stats

Add support to request transmit selfgen stats from firmware through HTT stats
type 12. These stats give information about single user NDP packets, multi-
user MIMO NDP packets, OFDMA triggers, etc.

Sample output:
-------------

cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats
