shared: add nm_g_type_find_implementing_class_for_property() helper

A helper method, only useful for printf debugging -- and thus
unused in the source-tree.

It is relatively cumbersome to lookup the GType that implements
a property. For example, for NMDeviceBond.driver, it should return
NMDevice (which implements the "driver" property).
