fix: account for jsx imports in config bundling

[jxom]

Description

Seems that when importing JSX files in vite.config.{js.ts}, the injection of file scope variables do not work. This PR fixes that.

Example

// foo.tsx
console.log(import.meta.url)
//          ^? ReferenceError: __vite_injected_original_import_meta_url is not defined

// vite.config.ts
import './foo'

Thanks for fixing this!

Hmm we don't really explicitly support JSX in config files and I don't think we should fix any edge case related to it. Otherwise it'll be hard to move to another tool that loads JS or TS for Vite (since Vite's config loading is known to be problematic in some case too)
