[PM-328] Move common/importer to libs/importer (tools-migration) (#5060)

* Create and register new libs/importer

Create package.json
Create tsconfig
Create jest.config
Extend shared and root tsconfig and jest.configs
Register with eslint

* Move importer-related files to libs/importer

* Move importer-spec-related files to libs/importer

Move import.service.spec

* Update package-lock.json

* Set CODEOWNERS for new libs/importer

* Register libs/importer with cli and fix imports

* Register libs/importer with web and fix imports

* Move importOption into models

Rename importOptions to import-options

* Fix linting issues after updating prettier

* Only expose necessary files from libs/importer

Fix tsconfig files
- Removes the trailing /index on imports in web/cli

As the spec-files no longer can access the internals via @bitwarden/importer they import by path (../src/importers)

* Add barrel files to vendors with more than one importer
