Eevee: World nodetree gpumaterial compatibility.

- Unify GPUMaterial creation (world/mesh).
- Support for multiple shader variations (not used for now).
- Convert GPUInputs to DRWUniforms to be used with the draw manager.
- Nodetree Update is not supported. The only way to refresh the shaders is to change render engine.
- Cleanup in GPUPass.
- Add new temporary Node Compatibility type. Compatibility types should be removed in the future.
