3c5749f862 General maintenance for plumbing (#94427)
## About The Pull Request
The overall behaviour of everything should stay the same but the memory
& speed of these components has been slightly improved and when you
scale that across large plumbing factories you get a substantial
improvement. Here's a list of the most noticeable changes along with
many others that aren't worth mentioning

- Removed vars `use_overlays`, `turn_connects`,
`recipient_reagents_holder`
- `active` var is now replaced with a proc which simply returns is the
machine wrenched or not
- `turn_connects` has been removed because all machines have their pipes
rotate when the machine is rotated. This also removed all the static
icon states ending with `-s` from the `dmi` file thus reducing that file
size as well
- `extend_pipe_to_edge` var is directly integrated into `cut_overlays()`
because it's use cases were limited such for showers & sinks
- Simplified `Initialize()` a lot. Removed params `start`,
`turn_connects`, `custom_receiver`, `extend_pipe_to_edge`. We now only
pass `bolt_layer` making that proc faster & less convoluted
- Replaced `set_recipient_reagents_holder()` proc with
`recipient_reagents_holder()` which returns the reagent holder for
holding reagents instead of storing it in the component. This removes
the need to hook a qdel signal on the holder & we don't need to keep
track of it
- Merged a ton of procs to reduce overhead & reduce file size
- Plumbing ducts creating the network at mapload is faster without using
recursion and the timer subsystem
- Deconstructing plumbing ducts is faster in reconstructing the network
without using recursion and the timer subsystem

This makes managing plumbing code less convoluted & overall better for
the foreseeable future. See the lines of code removed vs added and still
preserves behaviour

## Changelog
🆑
qol: added examines & screentips for ducts & stack of ducts
qol: you can wrench a stack of ducts on the ground to create a pipe
refactor: plumbing code has been improved overall. Report bugs on github
sprite: removed unused static(does not rotate with machine) icon states
for plumbing connections
