Module Resolver: Virtual test-support.css

[BlueCutOfficial]

This PR replaces the assets/test-support.css file generated in the rewritten-app with an entrypoint returning a virtual CSS:

- <link integrity="" rel="stylesheet" href="/assets/test-support.css">
+ <link integrity="" rel="stylesheet" href="/@embroider/core/test-support.css">

The content that was previously written in assets/test-support.css is now generated by the virtual-test-support-styles's functions.

How to test

• On the main branch:
  • Start the vite-app and visit http://127.0.0.1:4200/tests/
  • Search for the test-support.css file in the network tab
• On the present virtual-test-support-styles branch:
  • Start the vite-app and visit http://127.0.0.1:4200/tests/
  • Search for the test-support.css file in the network tab
• 👀 The response should be the same CSS content for both branches
• On the present virtual-test-support-styles branch:
  • Build the vite app in test mode (pnpm vite build --mode=test)
  • 👀 There should be a fingerprinted dist/assets/test-*.css containing the styles.
  • 👀 The stylesheet pointing to this file should be present in dist/tests/index.html
