kernel - Beef up vm_contig allocation checks
* Beef up vm_contig allocation checks by also requiring the PQ_CACHE page
to not be held or wired or unmanaged, and assert that it is not mapped
* When utilizing PQ_FREE pages ignore any held pages and assert that
the pages are not dirty in addition to not having an object.
* Do not clear PG_SBUSY when allocating a page (though it shouldn't be set
anyway, we still shouldn't unconditionally clear the bit).
