wifi: ath12k: add support for collecting firmware log
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.
