fix: context.multiline now bubbles up through child-contexts

[manuel3108]

This is an implementation detail. Will be helpful for a svelte print() related pr, that I will link in a moment (sveltejs/svelte#17319).

Let's assume this:

const context = ; // you get that from sowhere
const child_context = context.new();
child_context.newline();
context.append(child_context);

// before this pr
console.log(context.multiline); // false

// after this pr
console.log(context.multiline); // true

This is probably just an oversight from the 2.0 rework. The parent will always be a multiline-block as soon as it's children are. Apparently this is not covered by tests, no clue how to add a matching one.
