Support for React Server Components

Describe the feature you'd like:

As a user of react 18 with NextJS (with app directory), I would like to render async server components

example:
// Page.tsx

const Page = async ({ params, searchParams }: PageProps) => {
    const asyncData = await fetchSomeDataAsynchronously()
    return (<foo {...asyncData} />
}

...
// Page.test.tsx

it('should render', () => {
    render(<Page />)
    expect(screen....).ToBe(....)
})

Extracting server page logic would be an alternative, but I think that would also significantly reduce the purpose of RTL if that were to become an encouraged architectural default.

Current progress, workarounds, and demo

Start with the Page.tsx and Page.test.tsx examples, then review the linked current-progress, workaround, and demo comment. Done means establishing a supported way to render and test an asynchronous React Server Component with the requested behavior.
