 - 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. Release Notes: - N/A
