wifi: ath11k: add WMI_TLV_SERVICE_EXT_TPC_REG_SUPPORT service bit

Firmware advertises support for SERVICE_EXT_TPC_REG via a WMI service bit.
Add the definition of this service bit so that a subsequent patch can
check whether or not firmware supports this service.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
