wifi: iwlwifi: mvm: vif preparation for MLO

In MLO, some fields of iwl_mvm_vif should be defined in the
context of a link. Define a separate structure for these fields and
add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy
code will use only deflink object while MLO related code will use the
corresponding link from the link array.

It follows the strategy applied in mac80211 for introducing MLO
changes.

The below spatch takes care of updating all driver code to access
fields separated into MLD specific data structure via deflink (need
to convert all references to the fields listed in var to deflink.var
and also to take care of calls like iwl_mvm_vif_from_mac80211(vif)->field).
