wifi: ath12k: parse and save hardware mode info from WMI_SERVICE_READY_EXT_EVENTID event for later use

WLAN hardware might support various hardware modes such as DBS (dual
band simultaneously), SBS (single band simultaneously) and DBS_OR_SBS
etc, see enum wmi_host_hw_mode_config_type. Firmware advertises actual
supported modes in WMI_SERVICE_READY_EXT_EVENTID event. For each mode,
firmware advertises frequency range each hardware MAC can operate on.
In MLO case such information is necessary during vdev activation and
link selection (which is done in following patches), so add a new
structure ath12k_svc_ext_info to ath12k_wmi_base, then parse and save
those information to it for later use.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
