When a component is in runes mode and not using slots or events, adjust the output to only create the function type that mimics the underlying real shape of components in Svelte 5. This is a breaking change because previously the type was enhanced such that it also had the legacy class shape. As a result, users now may need to switch to
typeof Component
when using the component inside types.Sadly, due to a combination of requirements and TypeScript limitations, we need to always create both a legacy class component and function component type.
