qcacmn: Critical update signaling for beacon

Critical update is the explicit signaling for STA to notify
any change in BSS param.

There are two categories of critical update params.
Category 1 elements:  CSA, ECSA, Quiet, Quiet channel,
            Max Ch Switch Time, that are directly included in
            the per-STA profile of partner AP.
Category 2 elements: Except category 1 all operational IEs
           HT/VHT/HE/EHT and WMM/EDCA/MUEDCA params.

Defined below vdev flags to track change in Category 1 and
Category 2 CU params per ML VDEV
WLAN_VDEV_OP_CU_CAT1: Change in category 1 param
WLAN_VDEV_OP_CU_CAT2: Change in category 2 param

Host notify to FW by updating current link CU param in
wmi_bcn_tmpl_ml_info TLV of BCN TMPL CMD.
Set the corresponding cu_vdev_map category 1 / category 2
based on change in critical update params of ML VDEV.
