Right now, if you model something like this box with a button:

Let's say you want to pattern the button, and repeat it a second time. If you try, you'll actually pattern the entire model (box + button).

Why? Because right now, when you sketch on a face (like the button was), both the box and the button share the same ID. All extrusions from a solid will share the same ID, because they all refer to the same composite solid.
This is helpful in some ways -- arguably the solid _is_ just one big complex shape now -- but it's not helpful in other ways. What if I want to only pattern the button? Luckily there's an original ID for the button part, which is still stored. So we just need a way to tell the pattern stdlib functions whether to use the target's main ID or its original ID. This PR adds a new optional bool, `useOriginal`, to patterns. It's false by default, to keep backwards-compatibility (make sure that old KCL code doesn't change).
This PR is based on https://github.com/KittyCAD/modeling-app/pull/3914. It's based on work Serena and I are doing to fix a bug (engine does not allow patterning a 3D solid which was sketched on a face of another solid). @gserena01 our test program is now:
```
w = 400
case = startSketchOn('XY')
|> startProfileAt([-w, -w], %)
|> line(endAbsolute = [-w, w])
|> line(endAbsolute = [w, -w])
|> line(endAbsolute = [-w, -w])
|> close()
|> extrude(length = 200)
bump1 = startSketchOn(case, 'end')
|> circle({ center = [-50, -50], radius = 40 }, %)
|> extrude(length = 20)
// We pass in "bump1" here since we want to pattern just this object on the face.
useOriginal = true
target = bump1
transform = {
axis = [1, 0, 0],
instances = 3,
distance = -100
}
patternLinear3d(transform, target, useOriginal)
```
If you change the `useOriginal = true` to `false` you can see the difference.
