mm: remove inc/dec lruvec page state functions

Patch series "Remove some lruvec page accounting functions", v2.

Some functions are now unused; remove them.  Make
__mod_lruvec_page_state() unused and then remove it.

This patch (of 6):

All callers of these have been converted to their folio equivalents.
