Bug 1489010 - Remove XPIDL support for Null and Undefined value-taking properties on DOMString parameters and attributes. r=jorendorff

Browse Source 
These properties were added in bug 478251 back when XPIDL was sort of emulating
WebIDL. They are not needed any more, and none of our XPIDL files use them.
