Allow the 2XX code to be defined in successful Form Actions

Describe the problem

An api called through a Form Action might return any 2xx Success status code.

Currently, if an Action is successful and returns a data object, it can only return a 200 code.

Unlike the failure type, it does not appear that the status can be altered.

As far as I can tell, the only option I have available is to add a custom status: 2xx to the return object and retrieve it via data.status

Describe the proposed solution

It would be nice to see an option to provide a similar pattern as is made available via fail. Something like:

+page.server.ts

import { fail, succeed } from '@sveltejs/kit';

(...)

if (error) {
    return fail( 500, { error } )
};

return succeed( status, { data } );

actions.js

if (!data.status){
    return {
	type: 'success',
	status: 200,
	data
}
return {
    type: 'success',
    status: data.status
    data: data.data
}

Start at packages/kit/src/runtime/server/page/actions.js around the successful action handling referenced in the issue, and compare it with the existing fail pattern. Define how a successful Form Action can preserve a caller-provided 2xx status while retaining 200 as the default; done means the response status and returned data follow that behavior.
