USD.owl now uses self-hosted DUL version

This fixes an error with the CI, which throws an exception if one of the ontologies imports another that is not self-hosted.

To this end, the core vocabulary of USD is defined in terms of an upper-level ontology. In addition, a set of re-usable built-in schemata that are used in the USD language to describe prims are defined. In order to fasciliate translation, the ontological model attempts to replicate the structure of USD as closely as possible while in addition entailing semantics of USD entities.</rdfs:comment>
