[Feature?]: disable ssr for some pages

Duplicates

• I have searched the existing issues

Latest version

• I have tested the latest version

Summary 💡

currently we can do this:

function Home() {
  return <h1>Home</h1>;
}

import { clientOnly } from "@solidjs/start";

export default clientOnly(() => Promise.resolve({ default: Home }));

but this doesn't work the same as ssr: false
in ssr: false, initial data fetching happens on the client
with clientOnly data is initially brought by the server

Examples 🌈

No response

Motivation 🔦

No response

Start with the clientOnly usage and the @solidjs/start entry point shown in the issue, then compare its server data behavior with the requested ssr: false semantics. Define the supported page-level API and verify that initial data fetching occurs on the client.
