wifi: ath12k: add handler for WMI_VDEV_SET_TPC_POWER_CMDID

Browse Source 
Add the handler for WMI_VDEV_SET_TPC_POWER_CMDID, it is for 6 GHz band.
A subsequent patch will call this handler to send power parameters to
firmware.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
