Minor page tables improvements.
* Make split safe.
* Enable looking up next valid address.
* Support mappings with !accessType.Any(), distinct from unmap.
These changes allow for the use of pagetables in low-level OS packages, such
as ring0, and allow for the use of pagetables for more generic address space
reservation (by writing entries with no access specified).
Updates #5039
