Make JS APIs available to plugins and configs in the Standalone CLI (#15934)
This PR ensures we bundle the relevant JS APIs in the Standalone CLI
like `tailwindcss`, `tailwindcss/plugin`, `tailwindcss/colors`, etc…

Before, when loading plugins or configs, imports for those resources
would fail.

Fixes #15235
