rS349031: Change the arm64 pmap so that updates to the global count of wired pages are

Summary

Change the arm64 pmap so that updates to the global count of wired pages are not performed directly by the pmap. Instead, they are performed by vm_page_free_pages_toq(). (This is the same approach that we use on x86.)
