wifi: ath12k: Support Pdev Scheduled Algorithm Stats

Add support to request scheduled algorithm stats from firmware
through HTT stats type 49. These stats give information such
as count of DLOFDMA enabled, disabled, probed and monitored
based on rate and latency, consecutive number of MPDUs tried
and succeeded, etc.

Note: WCN7850 firmware version -
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
does not support HTT stats type 49.

Sample output:
