HexCasting port to 1.21 (NeoForge part)

[slava110]

Fabric is commented out.
This PR is based on my NeoForge repo of HexCasting. Some NeoForge leaked to XPlat. This should be easily fixable though.

Requirements

This port requires version of Paucal with gamma-delta/PAUCAL#12 and gamma-delta/PAUCAL#13. You can build it yourself, publish to maven (local or remote).

Notable changes

• Added Codecs to everything c:
• Tag representation of iotas has been removed. They are deserialized using Codecs, accessed in ItemStacks through data components, in block entity via field.
• EntityIota is reference-based now. Instead of directly referencing Entity object, its stores entity UUID and cached actual entity. This mechanism allows safely unloading and loading entities again without losing reference to them. Besides that it's just simply a necessity with Codecs.
• All List<Iota>.getEntity methods now require ServerLevel as argument due to the change above.
• Garbage and Null iotas are actually singletons now
• Iotas now store values inside subtypes. Hashcode is marked as abstract in superclass so users know that it should be overriden.

Requires attention

• Rendering-related anything. I'm not an expert in rendering and VCDrawHelper might have been ported poorly
• Datacomponent-related anything.

What’s current state on this?
Is it playable (as in — does it boot and work at least a bit)?
I am okay with bouth playing with partualy broken mod and regulary reporting bugs.

@User-green it works on NeoForge only and not this repository. Annoyingly broken architectury plugin doesn't allow me to port the mod properly to XPlat, so I've delegated porting to XPlat to other devs when they will be available. For now you can play with:
https://github.com/slava110/PAUCAL/releases/
https://github.com/slava110/NeoHexCasting/releases/
Don't forget Inline, Caelus, all the usual stuff. And it's in alpha state, expect bugs and problems. Especially with stuff related to items or EntityIota or more.

I am okay with crashes. Any bugs found will be reproduced and reported. Thank you

Seems like Scribe's Reflection no longer works on Ancient Scrolls. I gave myself one with /hexcasting perWorldPatterns give hexcasting:lightning (which interestingly also did seem to crash the game with Internal Exception: io.netty.handler.codec.EncoderException: Failed to encode packet 'clientbound/minecraft:system_chat').

@Sirius902, thanks for the report, fixed!
If possible, please direct other issues right to https://github.com/slava110/NeoHexCasting/issues so this PR draft is not filled with issue reports. Thanks!
