[REFACTOR] twenty-shared multi barrel and CJS/ESM build with preconstruct (#11083)

# Introduction

In this PR we've migrated `twenty-shared` from a `vite` app
[libary-mode](https://vite.dev/guide/build#library-mode) to a
[preconstruct](https://preconstruct.tools/) "atomic" application ( in
the future would like to introduce preconstruct to handle of all our
atomic dependencies such as `twenty-emails` `twenty-ui` etc it will be
integrated at the monorepo's root directly, would be to invasive in the
first, starting incremental via `twenty-shared`)

## How to test
In order to ease the review this PR will ship all the codegen at the
very end, the actual meaning full diff is `+2,411 −114`
In order to migrate existing dependent packages to `twenty-shared` multi
barrel new arch you need to run in local:
```sh
yarn tsx packages/twenty-shared/scripts/migrateFromSingleToMultiBarrelImport.ts && \
npx nx run-many -t lint --fix -p twenty-front twenty-ui twenty-server twenty-emails twenty-shared twenty-zapier
```
Note that `migrateFromSingleToMultiBarrelImport` is idempotent, it's atm
included in the PR but should not be merged. ( such as codegen will be
added before merging this script will be removed )

## Misc
- related opened issue preconstruct

## Closed related PR
- https://github.com/twentyhq/twenty/pull/11028
- https://github.com/twentyhq/twenty/pull/10993
- https://github.com/twentyhq/twenty/pull/10960

## Upcoming enhancement: ( in others dedicated PRs )
- 1/ refactor generate barrel to export atomic module instead of `*`
- 2/ generate barrel own package with several files and tests
- 3/ Migration twenty-ui the same way
- 4/ Use `preconstruct` at monorepo global level

## Conclusion
As always any suggestions are welcomed !
