libnm: fix nm-setting-docs.xml property types

Add nm_setting_get_dbus_property_type(), and use this to get the
correct type for properties in nm-seting-docs.xml, in situations where
the D-Bus and GObject property types don't match.

In the case of enum/flags-valued properties, give both the enum name
and the underlying D-Bus type.
