Overloaded registry members

[dktapps]

Blocks & items like wooden things might have different properties per wood type, so they're implemented as fully separate flattened blocks, like in vanilla.

However, we can avoid a lot of shitty code by auto-generating some simple functions that match an enum case to a block of a certain wood type.

The PR demonstrates this with VanillaBlocks::SIGN(WoodType $case) : FloorSign and VanillaItems::SIGN(WoodType $case) : ItemBlockWallOrFloor. A significant amount of boilerplate code is able to be deleted because of the additions of these simple functions.

This could be extended to all other wood-like blocks, but this PR mainly focused on a proof-of-concept to establish feasibility.

Future scope

• Extend to other wood blocks
• Better integration with regular registrations to avoid duplication of stuff like mb_strtolower($t->name) . "_sign") between overloaded member and actual registration
• Use this to de-shittify VanillaBlockMappings, which currently has to do a horrendous amount of this sort of copy pasta to implement each wood type
• Auto infer the overload's return type instead of requiring it to be specified explicitly

Tests

Tests are green. The code is used in the core, so it's established that it's working.
