Cleanup ext/dom: Removal of unimplemented dummy classes.

The following classes were registered in ext/dom but
neither documented nor had any behavior (only test data).
These classes are now removed:

- DOMNameList
- DomImplementationList
- DOMConfiguration
- DomError
- DomErrorHandler
- DOMImplementationSource
- DOMLocator
- DOMUserDataHandler
- DOMTypeInfo
