[Modding] Vanilla Items on Custom Player Models

[Jepvid]

This pr adds a system to make it possible to have custom player models use vanilla items. This is a major QOL thing for mod makers in the sense of not having to do duplicate exports of vanilla items to just match with the items.

It detects if there is custom hands in the alt path and if alt assets enabled then it will patch vanilla to have the custom hands and reverts back to normal if alt assets are disabled.

Claude have been used for finding when and where to noop the necessary parts of vanilla dls.

NOTE Models made with legacy fast64 have issues due to old materials exports. Its best to use models made with the latest fast64 where @Jameriquiah have fixed all those issues already

Needs testing done in order to make sure it wont cause crashes. Some testing done in anchor 2p anchor where i alt toggled and tested different items and seems good enough. someone else are free to test aswell

Curtesy of Jam here is a itemless Amara64 to test with this system.
