Description

Inspired by React Router's integration test (example), this PR setups more scale-able approach of testing different scenarios based on small number of templates.

The file structure looks like this:

• examples/e2e/temp
  • This is a base directory of test project. For example, this PR uses examples/e2e/temp/react-compiler, which is setup by setupInlineFixture utility. It uses examples/starter as a base project and additionally it replaces vite.config.ts to setup react compiler plugin.
  • This whole directory is ignored, but each test project is run-able locally e.g. by
    pnpm -C packages/plugin-rsc/examples/e2e/temp/react-compiler dev
• examples/e2e/package.json
  • The dependencies for temp projects are listed here. For example, it has babel-plugin-react-compiler for the test above.

I likely do more iterations, but for now, this PR migrates custom base test and react-compiler test to this system. This allows cutting down test times since they only test based on examples/starter and not the huge examples/basic.
