Config API and Options Screen Redesign

[douira]

Also thanks to @KingContaria for writing code on which I based the forge mod config entrypoint loader. @IMS212 wrote the initial redesign of the options page.

There's a bunch of TODOs in the code that I want to address. Feel free to help me with them and I'll merge them into this PR.

The design of the page as well as the outwards facing API are open to feedback and remain subject to change until release.

fixes #2309
fixes #2831

After implementing dynamic value constraints in the slider and cycler control elements, the remaining TODOs are not necessary for the basic required features to work and it's ready for review. The requests for additions to the API were implemented.
The search bar is not yet functional, but we can simply remove that without regressing the UX and add it when it gets implemented later. @KingContaria mentioned he wanted to work on the tooltip scroller and I plan on slowly working through the other remaining non-essential TODOs, which are related to UX/UI.
One thing I can't do and should be clarified before we release, is the automatic import of vanilla options into our options screen that @IMS212 had prototyped. I don't have that code but would integrate it if provided with it.

I've been provided by IMS's code to import vanilla options but haven't worked through that yet. @KingContaria contributed scrollable tooltips and I further reworked tooltip and donation button rendering.
