wifi: ath12k: Add support to RTT stats

Add support to request RTT stats from firmware through HTT stats type 65
and 66. HTT stats type 65 support RTT response stats, RTT hardware stats,
RTT to-be-read self-generated stats and RTT command-result stats and HTT
stats type 66 support RTT initiator stats and RTT hardware stats. These
stats give information about number of scheduled commands, responder
allocation and termination count, initiator termination count, PASN
authentication drop and receive counts, etc.

Note: WCN firmware version -
WLAN.HMT.1.1.c5-00284.1-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 does not support
tags HTT_STATS_PDEV_RTT_RESP_STATS_TAG(194),
HTT_STATS_PDEV_RTT_INIT_STATS_TAG(195),
HTT_STATS_PDEV_RTT_HW_STATS_TAG(196),
HTT_STATS_PDEV_RTT_TBR_SELFGEN_QUEUED_STATS_TAG(197) and
HTT_STATS_PDEV_RTT_TBR_CMD_RESULT_STATS_TAG(198), currently.
