Allow for bundling of worker scripts during dev

[schickling]

Description

Vite's dynamic import system is great for most frontend development use cases however in some situations e.g. when developing complex worker scripts, it might be preferable to bundle the worker scripts even during development as starting a worker (e.g. via new Worker('....')) can be significantly (e.g. multiple seconds) slower.

Suggested solution

It would be great if there was an option to continuously bundle worker scripts during yarn dev (even if that means features like HMR etc won't work)
