wifi: mt76: mt7615: enable BSS_CHANGED_MU_GROUPS support

Browse Source 
The Group ID Management frame is an Action frame of category VHT.
It is transmitted by the AP to assign or change the user position
of a STA for one or more group IDs.

Also, sniffer can use a given group id to monitor STA that belongs
to that group.

Notify underlying driver of changes via BSS_CHANGED_MU_GROUPS.
