vm_map: Add a map entry kind that can only be clipped at specific boundary.

The entries and their clip boundaries must be aligned on supported
superpages sizes from pagesizes[].  vm_map operations return Mach
error KERN_INVALID_ARGUMENT, which is usually translated to EINVAL, if
it would require clip not at the boundary.

In other words, entries force preserving virtual addresses superpage
properties.
