a wired, copy-on-write mapping are changed from read-only to read-write.

shared shadow vm object invalidation regression test
Add a regression test for a scenario where a shadow vm object is shared
by multiple mappings. If a page COW occurs through one of the mappings,
then the virtual-to-physical mapping may become invalidated.
This tests the scenario from CVE-2021-29626 which was fixed by
982693bb729badac4e65ecd59772979f2849a2b2.
