Turnstile improvements -- Construction graph, Sprite separation, Security upgrade -- Part 1

About the PR

Atomizing #37350

Makes constructing and deconstructing turnstiles more like regular airlocks.

Adds more steps, materials, and uses door electronics in order to have user-configurable access using a multitool.

Adds higher security versions with a welded steel plate and/or electrified wires. The electrification comes from the wire node underneath it. (Note that currently you do not need insuls to bypass this, see #37625 )

Also clean up some of the animation code and split out different parts of the turnstile sprite in anticipation of future parts implementing more of #37350

Why / Balance

Turnstiles are way too easy to deconstruct, and once deconstructed, simple engineers cannot properly set the proper access requirements.

Technical details

Mostly YAML changes.

The rest is just splitting up the sprites and then cleaning up some of the animation code to control the individual sprite component animations.

Finish with screwdriver

Done!

Wire panel

The wire panel is quite bare currently, but this will be filled out in future parts, implementing more of #37350

Electric grille upgrade

Requirements

• I have read and am following the Pull Request and Changelog Guidelines.
• I have added media to this PR or it does not require an ingame showcase.

Breaking changes

The currently mapped entities of id TurnstileGenpopLeave and TurnstileGenpopEnter should work as is.

For mappers: consider if you want easy turnstile wires panel electrification upgrades by providing powered wires under security turnstiles.

Changelog
🆑

• tweak: Turnstiles are constructed/deconstructed more like airlocks
• add: Turnstiles require Door Electronics and access can be configured as usual with a multitool
• add: Turnstile wire panels can be upgraded with a steel plate and/or metal rods for electrified security grille. Electrification requires powered wires directly under turnstile.

Fixes #37225, partially fixes #37227

Code looks good

I'm not too sure how I feel about them being shocked with a wire underneath them, as most maps are likely to have idle wires under their turnstyles anyway. That being said if it doesn't affect regular usage then it should be fine. It just might need to be mentioned to mappers so they can ensure their turnstyles are all shocked or not.

The turnstiles itself doesn't become shock on touch. It's an electrified security grille to access the wires panel, and was a request from the other PR.

There currently is no entity prototype that starts in the high security variant, so if security wants their turnstiles upgraded, the wiring would have to be done by an engineer anyway.

Oh I didn't mean to change it, I was just saying how that feature should be advertised to map makers so they can add wires under their turnstyles if they want

I'll throw it in the changelog as well.

Also check in #37350 I have a pretty full guidebook entry on turnstiles with all my upgrades. I'll include it when all parts are merged:
