Expose the Vite dev server

Describe the problem

Telefunc cannot be used with SvelteKit because Telefunc needs a reference to the Vite dev server which SvelteKit creates at:https://github.com/sveltejs/kit/blob/cf5d4aa54c3824a93967abe8508931854cd30524/packages/kit/src/core/dev/index.js#L92.

(Telefunc needs the Vite dev server to be able to run vite.ssrLoadModule() in order to import.meta.glob('**/*.telefunc.*').)

Describe the proposed solution

Expose the vite dev server.

For reference this is how Telefunc integrates with vite-plugin-ssr: https://github.com/vikejs/telefunc/blob/ff196287342b4ea3addbc0e0a559eef680f73796/examples/vite-plugin-ssr/server/index.js

Note how the Vite dev server is set to telefuncConfig.viteDevServer here: https://github.com/vikejs/telefunc/blob/ff196287342b4ea3addbc0e0a559eef680f73796/examples/vite-plugin-ssr/server/index.js#L23

@benmccann mentioned that there is PR to make the Vite dev server accessible, any chance to get it merged?

I would like to run the dev server in-process; I don’t need access to the internals, an opaque function that takes (req, res, next) or Web Fetch versions would be fine. I guess this actually also asks for a programmatic interface to SvelteKit.

Going to close this now that we just use a regular Vite config
