KCL: More simulation tests (#4359)

Demonstrate simulation tests where we don't care about visuals, e.g. the double-map test. 

The `just new-sim-test` now accepts an optional argument, `render_to_png` which can be either  "true" or "false" (defaults to "true"). Tests like double_map that don't render anything can use false, rather than rendering an empty PNG with nothing in it.

This means the [tests under `no_visuals/`](https://github.com/KittyCAD/modeling-app/tree/v0.26.2/src/wasm-lib/tests/executor/inputs/no_visuals) can be entirely replaced by simulation tests. This is much better! For example, I moved `double_map.kcl` from a no_visuals test to a simulation test. Here's the file:

```
fn increment = (i) => {
  return i + 1
}

xs = [0..2]
ys = xs
  |> map(%, increment)
  |> map(%, increment)
```

Previously the `no_visuals` test just checked that the program ran successfully without panicking. Now the simulation test lets you see the value of `xs` and `ys` and immediately see they're correct. If our map logic changes (for example, we have an off-by-one error and don't apply the `map` to the last element) it'll show up in the program memory snapshot.
