fix: remove unnecessary code

Now that we are prebundling, and can turn on npdejs_compat, some of the hacks from before are no longer needed.

- remove the fake process global
- remove the workerd custom import module
- remove the unsafeUseModuleFallbackService property
- consolidate environment options creation
- move vite override to the workspace catalog
