rG6b3897408521: vm_object: Modify various drivers to allocate OBJT_SWAP objects

Summary

This is in preparation for removal of OBJT_DEFAULT. In particular, it
is cheap to check whether an OBJT_SWAP object has any swap blocks
allocated, so the benefit of having a separate OBJT_DEFAULT type is
quite marginal, and the OBJT_DEFAULT->SWAP transition is a source of
bugs.
