Support SSR in plugin-vue-jsx

Describe the bug

Vite is unable to SSR when using jsx/tsx style Vue components. I have been told by a Vue maintainer this is is because @vite/plugin-vue-jsx is failing to inject modules into ssr context. Please see original issue for more context

Reproduction

Please provide a link to a repo that can reproduce the problem you ran into.

https://github.com/seanaye/vue3-tsx-tailwind

1. clone
2. yarn
3. yarn dev
4. open localhost:3000

Cannot read property forEach of undefined

I previously assumed this error came from renderToString from @vue/server-renderer, see line 16 of entry-server.ts. Apparently this comes from the jsx plugin not injecting modules into ssr context.

System Info

• vite version: 2.0.0 beta 65
• Operating System: Mac OS Big Sur M1 Chip
• Node version: 15.3.0
• Package manager (npm/yarn/pnpm) and version: yarn 1.22.10

I think I will try my hand at a PR for this tomorrow. Would love to contribute to such an awesome project

@yyx990803 I think it’s getting very close. Using with the latest vite core gives following error. Maybe this is a vue-router issue now and not a vite one?
