✨ feat(bs.block): add redstone related features

[aksiome]

Description

This PR replaces the is_conductive and is_spawnable functions by predicates.

It also adds 3 new predicates related to redstone:

• is_powered
• is_strongly_powered
• is_weakly_powered

and 3 new functions:

• is_touching_power
• is_touching_strong_power
• is_touching_weak_power

It also reorganizes things slightly by moving internal .json files into an internal folder.

This is something we should discuss for other modules as well. For now, there’s no overlap between functions and function tags since all our functions are considered private. However, for other resources like block tags and predicates, I think the header alone isn’t enough to indicate what counts as a feature.

I’m generally not a fan of visibility by naming, but it’s starting to feel necessary, and internal seems like the best term for it.
