Removes Pillar. (#12977)

* Removes Pillar.

I suppose this is my lesson to never trust people who claim they'll address issues later, because Pillar is a pile of issues that have been unaddressed since it's inception, despite my countless attempts (and growing frustration with) getting them handled.

There's too many issues to list here, so I'm just fully removing the map. Pillar will not be re-added without every single issue being addressed _at the time of PR_ and will be given zero leeway with leaving issues to solve later, because they clearly will never be solved.
