Get info from the GPU world

[rosofo]

We get a decent look at the JS side of execution in the graph, but not much feedback from GPU land except for shader compilation errors (does that count?)

• How much insight is it possible to get? Does WebGPU give us some hooks?
• How should we display the info? Depending on what we can do it might be nice to have a "GPU World" part of the graph, a box with some non-js objects and maybe even how the js ones correspond to them
