For MLO SAP, it can't generate beacon template until all the vdevs
start. To synchronize MLO vdevs start, we add two new substates
WLAN_VDEV_SS_MLO_SYNC_WAIT and WLAN_VDEV_SS_UP_ACTIVE whose parent
state is WLAN_VDEV_S_UP.
Once vdev gets vdev start rsp, notify MLO mgr, who checks whether all
vdevs are active, if so, trigger WLAN_VDEV_SM_EV_MLO_SYNC_COMPLETE for
the vdev which is in WLAN_VDEV_SS_MLO_SYNC_WAIT state.
After vdev translates to WLAN_VDEV_S_UP, MLO SAP will translate to
WLAN_VDEV_SS_MLO_SYNC_WAIT, while the other vdev will translate to
WLAN_VDEV_SS_UP_ACTIVE.
MLO sap will notify MLO mgr once it is in WLAN_VDEV_SS_MLO_SYNC_WAIT.
Then MLO mgr checks whether all the vdevs are active, if so, trigger
WLAN_VDEV_SM_EV_MLO_SYNC_COMPLETE for the vdev which is in
WLAN_VDEV_SS_MLO_SYNC_WAIT state.
If MLO SAP receives WLAN_VDEV_SM_EV_MLO_SYNC_COMPLETE in
WLAN_VDEV_SS_MLO_SYNC_WAIT state, it translates to WLAN_VDEV_SS_UP_ACTIVE
