wifi: cfg80211: allow devices to advertise extended MLD capa/ops

For UHR, multi-link power-management capability lives there, and so it's needed that hostapd knows what to advertise, and clients should have it shown to userspace for information. Repurpose the existing NL80211_ATTR_ASSOC_MLD_EXT_CAPA_OPS by renaming it to NL80211_ATTR_EXT_MLD_CAPA_AND_OPS (with a define for compatibility) and advertise the capabilities. We can also later use the value, if needed, to set per-station capabilities on STAs added to AP interfaces.
