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"
