- Adds the Switch component
- Updates `Selected`, `Selectable` -> `ToggleState`, `Toggleable`
- Adds `checkbox` and `switch` functions to align better with other
elements in our layout system.
We decided not to merge Switch and Checkbox. However, in a followup I'll
introduce a Toggle or AnyToggle enum so we can update
`CheckboxWithLabel` -> `ToggleWithLabel` as this component will work
exactly the same with either a Checkbox or a Switch.

While working on Assistant2, I noticed that the `LanguageModelSelector`
was recreating its `Picker` view on every single render.
This PR makes it so we create the view once and hold onto it in the
parent view.

This PR factors the language model selector out into its own
`language_model_selector` crate so that it can be reused in
`assistant2`.
Also renamed it from `ModelSelector` to `LanguageModelSelector` to be a
bit more specific.
