CreateNewResourceType(): support resource name on creation immediately

ABI backport. In nx-libs as of 3.5.99.3, you have to set a resource name with RegisterResourceName() after having it created with CreateNewResourceType().

With later X.org versions, the RegisterResourceName() call is obsolete, as the naming directly happens in CreateNewResourceType().

This is a reminder bug (cloned from #309) targetting the 3.7.x release series.
