SyncIt21 354e75026d Power machines can now operate on different cable layers (#76075) 
## About The Pull Request

Machines that require a cable underneath it to operate like Tesla, SMES,
Emitter & Turbine now look for the `cable_layer` (red, yellow, blue
default being yellow) to operate on and not `machine_layer`(that var is
removed). `machine_layer` & `cable layer` served the same purpose so i
removed `machine_ layer` var and made it just look for the cable layer
to operate on to reduce redundancy.

The following machine's can have their cable layer changed with a
multitool when in the specified state
1. Emitter when it's not welded
2. Tesla Coil when it's not wrenched
3. SMES when it does not have a terminal attached
3.1 Terminal of the SMES cable layer can also be changed with Right
Click during installation
4. APC terminal cable layer can also be changed with Right Click during
installation
5. Turbine rotor when its panel is open


![POWER](https://github.com/tgstation/tgstation/assets/110812394/21827905-0a46-43de-8626-489e773c370a)
Here all 3 SMES were on 3 separate layers of cable but they were all
joined by a single multi z layer hub cable summing up all their
contribution's even though they were on different cable layers.


##  Why It's Good For The Game
It makes sense that a machine should only look for what cable layer it
should operate on and adding another layer called machine layer was just
redundant. Also cable layers blue & red which could not be used by
machines are now usable

## Changelog
🆑
fix: cable layers 1 & 3 can now be used by machine's like emitters,
smes, tesla coil & turbine.
fix: terminals(smes & apc) can operate on different cable layers by
installing them with right click
