wifi: ath12k: Support phy counter and TPC stats

Add support to request counters and Transmission Power Control
(TPC) stats through HTT stats type 37. These stats give
information about counters like received packet count, CRC pass
count, error count, transmit abort count, etc., about counter reset
like reset cause, channel frequency, number and mode, channel flags,
etc., about TPC like transmit power scale, maximum transmit power,
gain cap, EIRP, etc.

Note: MCC firmware version -
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 does not
support HTT stats type 37, i.e., the firmware does not respond to the
command requesting stats.
