Introduce vm_page_grab_pages(), which is intended to replace loops calling
vm_page_grab() on consecutive page indices.  Besides simplifying the code
in the caller, vm_page_grab_pages() allows for batching optimizations.
For example, the current implementation replaces calls to vm_page_lookup()
on consecutive page indices by cheaper calls to vm_page_next().
