[1.21.4] Expose vanilla model generators for modded usages

[ApexModder]

Updated version of #1696 for 1.21.4.

While the vanilla providers have been exposed for modded usage, and can be used for more simpler model generation. This is still highly WIP and requires more patches to support our model extensions and generating a model from scratch.

Merged in @XFactHD fork, everything should be exposed and usable. Test mod datagen just needs rewriting to now use vanilla model providers.

This PR should now be ready for view but important note ExtendedModelTemplate.Builder may still get some major reworking to lessen the amount of nesting/.end calls.
Thinking of refactoring into lambda style rather than builder style.

Meaning that the following
ExtendedModelTemplate.builder().element().end()

would change to something like so
ExtendedModelTemplate.builder().element(element -> { })

A couple more comments, primarily about documentation.
When these are adressed, this PR is good to go from my end. The approval and merge has to be done by someone else as this PR adds code I wrote.

[ChampionAsh5357]

Just some quick comments based on my previous ones.
