SKA: Unify serverless modules + storybook config (elastic#211570)

## Summary

As part of the SKA, some groups of modules have been broken-down and
relocated in different folders, negatively impacting DX. This is the
case for `serverless` modules, that are spread across:
```
- packages/serverless  # storybook config
- src/platform/packages/private/serverless
- src/platform/packages/shared/serverless
```

The goal of this PR is to unify them back under
`src/platform/packages/shared/severless`.
In this scenario, I believe the simplification is worth the trade off.
