Reviewed by Tyler Wilcock.

In https://bugs.webkit.org/show_bug.cgi?id=265625 we addressed the issue of AX objects not being created for relation targets. This patch extends the fix for relation origins, which should also have an AX object. This problem became evident in WK1 where <input> elements may not have a renderer and therfore AXObjectCache::getOrCreate doesn't create an AX object for them.
