Curve gizmos integration (#14971)
# Objective

- Add gizmos integration for the new `Curve` things in the math lib

## Solution

- Add the following methods
  - `curve_2d(curve, sample_times, color)`
  - `curve_3d(curve, sample_times, color)`
  - `curve_gradient_2d(curve, sample_times_with_colors)`
  - `curve_gradient_3d(curve, sample_times_with_colors)`

## Testing

- I added examples of the 2D and 3D variants of the gradient curve
gizmos to the gizmos examples.

## Showcase

### 2D

```rust
    let domain = Interval::EVERYWHERE;
    let curve = function_curve(domain, |t| Vec2::new(t, (t / 25.0).sin() * 100.0));
    let resolution = ((time.elapsed_seconds().sin() + 1.0) * 50.0) as usize;
    let times_and_colors = (0..=resolution)
        .map(|n| n as f32 / resolution as f32)
        .map(|t| (t - 0.5) * 600.0)
        .map(|t| (t, TEAL.mix(&HOT_PINK, (t + 300.0) / 600.0)));
    gizmos.curve_gradient_2d(curve, times_and_colors);
```

### 3D

```rust
    let domain = Interval::EVERYWHERE;
    let curve = function_curve(domain, |t| {
        (Vec2::from((t * 10.0).sin_cos())).extend(t - 6.0)
    });
    let resolution = ((time.elapsed_seconds().sin() + 1.0) * 100.0) as usize;
    let times_and_colors = (0..=resolution)
        .map(|n| n as f32 / resolution as f32)
        .map(|t| t * 5.0)
        .map(|t| (t, TEAL.mix(&HOT_PINK, t / 5.0)));
    gizmos.curve_gradient_3d(curve, times_and_colors);
