Add support for passing named slots from `.astro` => framework components.
Each `slot` is be passed as a top-level prop. For example:
```jsx
// From .astro
<Component>
<h2 slot="title">Hello world!</h2>
<h2 slot="slot-with-dash">Dash</h2>
<div>Default</div>
</Component>
// For .jsx
export default function Component({ title, slotWithDash, children }) {
return (
<>
<div id="title">{title}</div>
<div id="slot-with-dash">{slotWithDash}</div>
<div id="main">{children}</div>
</>
)
}
```
