More positions for body scanners and sleepers when using a wrench

[Gatchapod]

What Does This PR Do

fixes #18797 Makes sleepers and body scanners use all four sprites when a wrench is applied to them. Removes a vestigial variable, orient, which wasn't actually doing anything.

Why It's Good For The Game

Someone was bothered by it enough to write a bug report. More options is generally a good thing, too.

Testing

Spawned in. Used a wrench on both machines. Confirmed both rotate properly. Successfully put a grey into both machines in all four positions.

Changelog
