For large XML schemas not all the types will be used.  A performance optimization would be to leverage lazy loading at the TreeObjectBuilder level.

Fix checked into 2.1.3 at rev:  9073

Code reviewed by:  Gordon Yorke

Changes:
- Added a property to XMLDescriptor called "isLazilyInitialized".  If this flag is true, then EclipseLink may lazily initialize the metadata.
- At this point TreeObjectBuilder is the only thing that is lazily initialized if this property is set.
- JAXB/OXM defaults to lazilyInitialized=false, and SDO defaults to lazilyInitialized=true
