Add a static JSX transform option

[aquapi]

What is the problem this feature would solve?

This feature will add a faster way to transform JSX to string on the server-side, Similar to Deno precompile JSX

What is the feature you are proposing to solve the problem?

A jsx transform option to convert JSX to array templates similar to Deno precompile feature

What alternatives have you considered?

Right now the fastest way to render jsx to string on the server is by using kitajs/html, but it uses react-jsx transform which is a lot slower and requires more code then the method above

Here's an example of how the compilation result should look like:

const text = Math.random() < 0.5 ? 'Hi' : 'Hello';
const element = <p class='text' id={text}>{text}</p>;

And an option somewhere (maybe tsconfig.json) that specifies:

{
  "jsx": "precompile",
  "jsxImportSource": "preact"
}

import { jsxTemplate, jsxEscape, jsxAttr } from 'preact/jsx-runtime';

// Store the template static parts
var tmpl = ['<p class="text" ', '>', '</p>'];

const text = Math.random() < 0.5 ? 'Hi' : 'Hello';
const element = jsxTemplate(tmpl, jsxAttr('id', text), jsxEscape(text));

Here's the details from Deno: https://deno.com/blog/v1.38#fastest-jsx-transform
