Changes the waxed copper blocks to have different textures for the sake of being able to tell them apart.
Also fixes a few minor vanilla texture errors related to copper:
MC-266244: "Weathered Lit Copper Bulb texture has compression artifacts"
MC-267299: "Chiseled copper texture has wrong lighting direction"
MC-268206: "Texture of Trial key inconsistent with textures of Trial spawner and Vault"
