Suggestion: Add Controllers for Entities, Particles, Blocks and Potion Effects

Similar to how ItemController allows selecting an item (or multiple when used with ListOption) it could be useful to have the same for Entities, Blocks, Particles, Potion Effects and other things that use the minecraft:minecraft_minecraft ID style.

This could be useful for disabling specific particles for example without requiring a full list of toggles for every particle.

For Blocks the side or front texture of the block would be the icon.
For particles the particle texture would be the icon. (some particles are rendered with a different color than their texture when displayed in game like sharpness particles, idk if would be possible to apply that to the icons in the config as well)
For Entities 3D models would probably cause lag so it would be better if the icon was the face of the Entity (idk how this would work for boats and minecarts and similar entities though)
For Potion Effects the icon would just be the effect icon.

Some other options could be Sounds, Dimensions, Biomes, Structures and Enchantments but I have no idea what the icons could be for those and I don't even know what I would use these for in a mod.

The issue does not name files or tests; begin by locating the existing ItemController and the controller API it uses. Compare how item selection and icons are implemented, then determine the scope and acceptance criteria for additional entity, particle, block, and potion-effect controllers. The issue currently leaves the design and definition of done unresolved.
