[MIRROR] Minor maintenance for plumbing (#28001)

* Minor maintenance for plumbing (#83629)

## About The Pull Request
**1. Qol**
 - Screentips & examines for welder, wrench & plunger tools
- Examining plumbing machinery will display the reagents & their
respective volumes present inside
- Plumbing grinder now has a grind/juice mode which can be changed by
hand

**2. Code Improvements**
- Rapid plumbing device now uses the new attack
chain(`interact_with_atom()` & `interact_with_atom_secondary()`) instead
of the general `attackby()`
 - Same attack chain improvements applied for plumbing grinder
- Plumbing grinder now processes items that enter into it asynchronously

**3. Fixes**
 - Fixes #83538. Contains various sub changes
- You can now attack the plumbing grinder with any item in combat mode
without the grinder trying to consuming it
- You can deconstruct the plumbing grinder with the Rapid plumbing
device without the grinder trying to consuming it
- You cannot grind abstract & hologram items in the plumbing grinder
- Growing vat now uses the correct layer selected on rapid plumbing
device

## Changelog
🆑
qol: more examines & screentips for plumbing machinery
qol: plumbing grinder has a grind/juice mode which be toggled by hand
code: improved attack chain for RPLD & plumbing grinder
fix: You can deconstruct the plumbing grinder with the RPLD
fix: You can attack the plumbing grinder with any item in combat mode
without getting that item consumed
fix: You cannot grind abstract/ hologram items in the plumbing grinder
fix: growing vat now uses the correct layer selected on rapid plumbing
device
