Wifi: Add support to query and use driver advertised interface combination

Interface combinations in legacy-hal is predefined with
'WIFI_HAL_INTERFACE_COMBINATIONS' build flag. Netlink interface
already provides supported interface combination via
'NL80211_CMD_GET_WIPHY' using attribute
'NL80211_ATTR_INTERFACE_COMBINATIONS' , thus build time dependency
to configure interface combination for each target can be removed
by querying the combination at runtime.
