Add submitting state to page store #7120
Description
Describe the problem
First, thank you for all of your work in SvelteKit.
It's common to disable the submit button during form submission to prevent users from submitting multiple times.
But now, we need some boilerplate code to do it. cf) #7041
It would be nice if SvelteKit provides the submitting state by page store.
Describe the proposed solution
$page.formSubmitting?$page.form.submitting?- and so on
<script>
import { page } from '$app/store'
</script>
<button disable={$page.formSubmitting}>submit</button>Alternatives considered

nice to have
Additional Information
FYI: Remix can handle it by the followings,
function SubmitButton() {
const transition = useTransition();
return <button type="submit" disable={transition.state === "submitting"}>submit</button>;
}
