wifi: drivers: indicate support for attributes in NL80211_CMD_SET_BSS

The command NL80211_CMD_SET_BSS has a number of individual attributes
and the driver can advertise which of those it will handle when it is
changed by user-space. For drivers providing an empty .change_bss()
the callback has been removed.
