feat: add workbox-build package

[userquin]

Description

This PR adds the workbox-build package:

• use valibot instead avj to validate options
• add vitest and validate tests
• removed webpack types

This PR also adds a new subpackage export (types) to some workbox packages.

TODO:

• 👉 update workbox-swkit to use workbox v7 instead v6 : workbox-core (replace self with globalThis), workbox-streams (concatenate changes) and workbox-strategies (now using Promise.allSettled at doneWaiting and improved error handling).
• remove magicast local tgz dependency once we've feat!: add introspection and improve proxy behavior unjs/magicast#136 merged and released (can take some time, the PR I've sent is huge)
• update tsdown dep at pnpm-workspace.yaml once merged and released: using pkg-pr-new from this PR fix(exports): correctly generate export paths for nested index files rolldown/tsdown#559
• ✔️ change repo and package names: @vite-pwa/sw-toolkit or just @vite-pwa/toolkit package renamed to @vite-pwa/workbox-swkit
• ✔️ move all client packages to only one
• use isolated declarations: no need, packages quite small (building @vite-pwa/workbox-swkit takes 1 second
• generateSW logic
• injectManifest logic
• getManifest logic
• test: check playwright/webdriverio service worker support:
  • https://playwright.dev/docs/service-workers-experimental
  • https://playwright.dev/docs/test-parallel#disable-parallelism
• test: check vite environment api to move service worker tests to vitest browser mode (to allow reload the sw => will require page reload when changed): check if msw can be disabled
• add CI tests

I'm going to merge this (initial minimal impl. for generateSW streategy), I want to change repo and package names first:

• workbox-build package will go to toolkit => @vite-pwa/toolkit (the only package required for vite-plugin-plugin: workbox-build and workbox-** packages in one package)
• workbox-build package will be the only package required for vite-plugin-plugin: workbox-build and sw-toolkit packages in one package)
• all workbox-** will go to sw-toolkit workbox-sw => @vite-pwa/sw-toolkit @vite-pwa/workbox-swkit (will include a barrel (.) including all the workbox-** packages and types ./types subpackages, export adding also every workbox-** as a subpackage exports for more granular imports
