iwlwifi: mvm: add support for 8 level scan priority API
Add support for scan priority API with 8 levels instead of the
existing 3 levels. This API is needed to define the priority of
new ooc activities, e.g. gscan.
Add a TLV flag to indicate if the new API is supported so that
devices that does not support the new API will continue to use
the old one.
