DPP: Allow version number to be overridden for testing purposes

Browse source 
"SET dpp_version_override <ver>" can now be used to request
wpa_supplicant and hostapd to support a subset of DPP versions. In
practice, the only valid case for now is to fall back from DPP version 2
support to version 1 in builds that include CONFIG_DPP2=y.
