Remove or disconnect some unused calls to ObjCObjectGraph::create

Reviewed by Brady Eidson.

The last use of WKConnection was removed in rdar://127167483.
This PR removes or disconnects the non-WKConnection uses of ObjCObjectGraph,
all of which are unused and have been for over a year.

_loadData SPI with userData is still used by Mail, but they only pass in an
NSData, so they don't need the full power of ObjCObjectGraph.  API::Data will do.
