fix: hmr on web worker

[userquin]

Description

Fix client and overlay modules for HMR on web workers.

This PR will be on draft since I need to add some test and what to do on clearErrorOverlay, line 200 of client.ts.

I just push it if anyone can review the changes on packages/vite/src/client.

I've included on worker playground 2 examples to update msg from workerImport module, also modified the index.html page to log HMR updates for my-worker (normal and inlined), possible-ts-output-worker and workerImport to avoid full reload.

Here you can check the HMR working with playground web workers: https://streamable.com/0gtb8d

We cannot use HMR on service workers since we cannot use dynamic imports yet on service workers.

I need to add tsconfig.json on workers playground to add "module": "esnext", maybe we need to review it since I can break tests.

Tested also on vue project to check it is not breaking anything (I cannot run vue playground, it is failing, see last screenshot):

The error on vue playground:
