qcacmn: Critical update signaling for beacon

Browse Source 
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.
