[MC-203222] SlotWrapper does nothing and obfuscates behavior

The following internal class does nothing based on its implementation, which is a pure class wrapper that adds 0 behavior. Including minuscule memory and performance implication, this wrapper slot actually adds minor developmental burden, as all slots in a creative inventory need to derive from it, because mouse interaction casts every slot into a creative slot (again, for no actual reason). For additional headache, the wrapper class inhibits some more specific modding attempts regarding the creative inventory.

Can confirm in 1.21.11, the decompiled bytecode proves that the wrapper is still a completely behaviorless delegator that adds unnecessary overhead:
