wifi: trace: unlink rdev_end_cac trace event from wiphy_netdev_evt class

rdev_end_cac trace event is linked with wiphy_netdev_evt event class.
There is no option to pass link ID currently to wiphy_netdev_evt class.
A subsequent change would pass link ID to rdev_end_cac event and hence
it can no longer derive the event class from wiphy_netdev_evt.

Therefore, unlink rdev_end_cac event from wiphy_netdev_evt and define it's
own independent trace event. Link ID would be passed in subsequent change.
