Shader defs on internal assets

[unborn gazelle]

I'm trying define some defs on a wgsl file loaded like: load_internal_asset!(app, UTIL, "../assets/shaders/util.wgsl", Shader::from_wgsl);
How can I do that?

Shader defs are usually set at the pipeline level, not the shader level (not sure if you can set them at the shader level)
