What the title says.
This does **not** migrate off of the legacy `Arrow3D`, that's for a
future PR.
---
Python:
```python
lengths = np.log2(np.arange(0, 100) + 1)
angles = np.arange(start=0, stop=tau, step=tau * 0.01)
vectors = np.column_stack([np.sin(angles) * lengths, np.zeros(100), np.cos(angles) * lengths])
arrows = [rrd.Arrow3D(origin=[0, 0, 0], vector=v) for v in vectors]
colors = [[1.0 - c, c, 0.5, 0.5] for c in angles / tau]
rr2.log("arrows", rr2.Arrows3D(arrows, colors=colors))
```
Rust:
```rust
let (arrows, colors): (Vec<_>, Vec<_>) = (0..100)
.map(|i| {
let angle = TAU * i as f32 * 0.01;
let length = ((i + 1) as f32).log2();
let c = (angle / TAU * 255.0) as u8;
(
Arrow3D::new(
Vec3D::ZERO,
[length * angle.sin(), 0.0, length * angle.cos()],
),
Color::from_unmultiplied_rgba(255 - c, c, 128, 128),
)
})
.unzip();
MsgSender::from_archetype("arrows", &Arrows3D::new(arrows).with_colors(colors))?
.send(&rec_stream)?;
```

) ### What Adds C++ example build setup and examples for: * Point3D #2789 * Arrow3D #2785 * DisconnectedSpace #2791 as before Point2D example is blocked on rects for the moment. Generating a bunch more methods now for better usability. Still lacking user extensions though, in particular Point3D construction is poor right now Examples can be built in bulk with ` ./tests/cpp/build_all_doc_examples.sh` Then run with `./build/tests/cpp/doc_example_point3d_EXAMPLE_NAME` They all connect to localhost on default port for now.

### What Introduces a simple extension system for C++ codegen: Add an extra cpp file that will be compiled as part of the SDK. A section between two markes is copied into the generated hpp as part of generation (typically this section is removed from compilation via #ifdef) Adds extensions to: * color * vec2/vec3/vec4 * quaternion * origin3d * point2d * point3d * arrow3d ... and uses them to simplify examples and test code! All fully supported archetypes now have a simple test that checks that the base interface works and that we can serialize out to arrow without issues. Additionally, there's tests for vecN/quaternion/color to check that their various constructors work as expected (not being a C++ expert it's fairly hard to predict) Extends codegen with single-array-field-constructors. --------- * part of #2647 * Fixes #2798 * Fixes #2785 * Missing only 2D example: #2789 * Adds to #2791 ### Checklist * [x] I have read and agree to [Contributor Guide](https://github.com/rerun-io/rerun/blob/main/CONTRIBUTING.md) and the [Code of Conduct](https://github.com/rerun-io/rerun/blob/main/CODE_OF_CONDUCT.md) * [x] I've included a screenshot or gif (if applicable) * [x] I have tested [demo.rerun.io](https://demo.rerun.io/pr/2916) (if applicable) - [PR Build Summary](https://build.rerun.io/pr/2916) - [Docs preview](https://rerun.io/preview/pr%3Aandreas%2Fcpp%2Fcustom-extensions/docs) - [Examples preview](https://rerun.io/preview/pr%3Aandreas%2Fcpp%2Fcustom-extensions/examples)
