[MIRROR] Late adjustments to my previous move_loop PR. [NO GBP] [MDB IGNORE] (#21730)

* Late adjustments to my previous move_loop PR. [NO GBP] (#75778)

## About The Pull Request
Lemon guy was a bit too late in reviewing #75732 because it got already
merged by someone else, and I too hadn't managed to make some adjustment
to that PR in time.

This PR applies suggested changes, turns a simple proc into a macro, and
makes it so that also waddling, squeaky shoes and swivel chair sounds
don't running when moved by conveyor belt.

This doesn't stop squeaking from happening when other
conveyor-belt-moved objects or mobs cross its tile. That'd be hacky and
I'm not here to fight sfx-spamming machines.

## Why It's Good For The Game
These are changes that should have been included in #75732 but couldn't.
See that PR for the general idea.

## Changelog

🆑
fix: waddling, squeaky shoes and swivel chair sound effects no longer
run when moved by conveyor belt.
