SkyratBot b6ffb1e31b [MIRROR] Refactor /turf/var/intact [MDB IGNORE] (#9114) 
* Refactor /turf/var/intact (#62331)

Turfs have a variable, intact, which conflates three meanings:

    Determining whether there's something that can be pried out, such as directly with a crowbar or indirectly with a tile stack and a crowbar off-hand.
    Determining whether underfloor pieces are visible.
    Determining whether underfloor pieces can be interacted with - by players with tools, through interaction with effects like chemical acid, or foam.

When plating is hit with a stack of tiles, /turf/open/floor/attackby checks whether the turf is intact, and if so, ends the attack chain regardless of whether or not the attempt to hotswap a turf (with a crowbar) is successful or not. However, turfs which want the underfloor to be visible - such as catwalks and glass - set the intact variable to FALSE, and so can be repeatedly placed over one another, as if they were the first tile to be placed over the plating.

This refactors /turf/var/intact into two distinct variables:

    /turf/var/overfloor_placed, for whether or not there is something over plating.
    /turf/var/underfloor_visible, for whether or not the various underfloor pieces should be invisible, visible, or both visible and interactable.

All references to /turf/var/intact have been replaced with an equivalent overfloor_placed or underfloor_visible reference, depending on which check is appropriate. underfloor_accessibility can take one of UNDERFLOOR_HIDDEN, UNDERFLOOR_VISIBLE, or UNDERFLOOR_INTERACTABLE. This prevents cases such as acid foam or tools phasing through glass floors to affect the underfloor pieces underneath, and covers all kinds of unusual, not-wiring-visiblity usage such as Holodeck completeness, Revenant interaction, or station integrity checking.

* Refactor /turf/var/intact
