Fix T98663: Eevee compilation error cryptomatte shaders.

On MacOS Eevee cyptomatte shaders fails as it doesn't ignore the `attrib_load`
parameter. I validated that removind the parameter works on Linux/AMD and MacOS
Intel. It could be that there are other platforms that require the dummy parameter.

If this should use a forward declaration and implement an emoty function in the
cryptomatte vertex shader.
