Breaking texture is small when breaking mob heads

When mining mob heads in survival, the breaking block texture is reduced by size in half and appears as a 32x32 texture. This is unlike the heavy core, which is the same 8x8x8 cube block model, but has a proper 16x16 breaking texture that cuts off at the edges. This affects the Player Head, Zombie Head, Creeper Head, Skeleton Skull, Wither Skeleton Skull, and Piglin Head
