Feature/registry classes

[ShaneBeee]

Description

This PR aims to create a new set of classes based around the Bukkit Registry class.
The registry classes are based around EnumUtils, EnumClassInfo and EnumSerializer

Bukkit plans on using more registry things in the future.
As of right now the biome registry doesn't support custom biomes, but I believe the plan is to make that happen with 1.21
This allows Skript to get on board with registries and support stuff before we're forced to.

I believe Bukkit is also planning to drop enums for registry based classes, ie: Biomes, and switching to actual classes with static fields.
Another reason to prepare for the future.

Building off the same base of my Enchantments PR, a few things to note:

• As with an enum, this registers names/patterns using lang file nodes
• If a lang file entry is missing (either wasn't added yet, or custom) the follow will be added:
  • if a minecraft value = the key of the object without underscores (ex: windswept hills) will be used as name
  • if a custom value = the full namespaced key will be used (ex: my_thing:hot_spicy_biome) will be used as name
• A full namespaced key for Minecraft/Custom objects will be added as a pattern
• Minecraft objects will have their key without spaces added as a pattern

I put this as a draft as I'm looking for feedback.
A lot was taken from the Enum classes for inspiration, but open to improvement.

I included registrant the Biome class info using this new method, to test/showcase how it works.
