wifi: iwlwifi: mvm: add support for the new MAC CTXT command

As a part of the new MLD FW API changes, we have a new MAC CTXT command.
Add structures and enum definitions, along with the functions that
sends this command (i.e. add, remove and change mac ctxt).
This functions will be in used in the next patches.
