wifi: ath12k: add support for collecting firmware log

Browse source 
Currently there is no way to collect firmware log because firmware
does not send it to host. Also host does not handle WMI_DIAG_EVENTID
which is used by firmware to upload firmware log.

So add support for it by firstly enabling firmware log upload via a
QMI message, and secondly processing WMI DIAG event to expose it to
userspace via trace event.

This change applies to both WCN7850 and QCN9274.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
