Svelte 5: scope is borked with slots and static props

[Rich-Harris]

Describe the bug

We set the child scope on the component node, for convenience, but that breaks when you combine slot props with static props of the same name:

<script>
	import Child from './Child.svelte';
	
	let thing = 'hello';
</script>

<Child thing={thing} let:thing>
	<p>thing: {thing}</p>
</Child>
