[NeoForge 1.21.1] Controlify integration for controller support

[EchoEllet]

Fixes #2116 and adds fully functional controller support.
This PR relies heavily on the refactored input system #2122, which was developed for 1.20.1 and subsequently ported to 1.21.1.

Also sent a PR to Epic Skills: Epic-Fight/epicskills#5

Quick Test

If you're a:

• player: download this zip file, drag and drop the JAR files in .minecraft/mods (NeoForge 1.21.1 only).
• developer: checkout this branch, change the controlify compileOnly line to implementation temporarily, then run ./gradlew runClient.

Screen support

• Skill Editor: Forced the virtual mouse behavior for the skill editor screen to save development overhead.
• Skill Book: Added full controller support for the skill book screen, since it has only one button, and it's pretty trivial to support.

This should be enough to make Epic Fight fully playable with a controller.

Release note entry

It might be worth adding this for addons:

**Important:** If you're a mod developer modifying Epic Fight’s `ControlEngine` using a mixin, please test your changes against the latest version to avoid breaking Epic Fight internals or your add-on’s behavior.
You may see some **deprecations** — please consider **migrating** to support controllers in future updates.
For more details, refer to [PR #2122](https://github.com/Epic-Fight/epicfight/pull/2122).
