pgsql: Rename LVRelState VM-related logging counters

Rename LVRelState VM-related logging counters

The LVRelState fields that track newly all-visible/all-frozen pages were
previously named vm_new_visible_pages, vm_new_frozen_pages, and
vm_new_visible_frozen_pages. The correct terminology is all-visible and
all-frozen; omitting “all” was open to misinterpretation, as the page
isn't visible or invisible, rather all the tuples on the page are
visible to all running and future transactions. Rename the members
accordingly.
