rG235750ee5130: vm: Remove kernel stack swapping support, part 8

Summary

The kernel stack objects do not need to be pageable, so use OBJT_PHYS objects instead. The main difference is that mappings do not require PV entries.
Make some externally visible functions private to vm_glue.c, as their external consumer is now gone.
