Fixes#1643
The dispatched `on:change` event in `Slider` only fires when the slider thumb is released. `on:input` fires when actively dragging the thumb, and should fire on every increment (e.g., 1, 2, 3).
The `bx--slider` class in the `Slider` component has max-width of `40rem`. Because `$$restProps` is spread to the top-level `div` element in `Slider`, the only way to override the style is to do so globally:
```css
:global(.bx--slider-container) {
width: 100%;
}
:global(.bx--slider) {
max-width: none;
}
```
This adds a `fullWidth` prop that sets a full width style using inline style attributes.
