rS363840: Remove most lingering references to the page lock in comments.
Summary

Finish updating comments to reflect new locking protocols introduced
over the past year. In particular, vm_page_lock is effectively unused
now. This diff does not modify comments relating to the busy lock,
which has also changed in scope.

There is one remaining comment that references the page lock, omitted
here because it corresponds to a (mostly harmless) bug in r356157. I
will fix it separately.
