Create an npm package for developing decoupled components

Background

We have some prior art with CKEditor 5 when working with npm packages and Drupal. Our current recommendation is to clone a starter project and use the webpack config and package.json from that. This prevents us from updating the dependencies or configuration quickly, as many versions are propagated through various contrib modules.

Proposed resolution

Drawing inspiration from @wordpress/scripts, develop an npm package with tooling for building and packaging decoupled components.

The MVP of this will include:

• A script for building JS and CSS

Out of scope but for future consideration:

• linting
• a script for checking license compatibility

Release this as a package on npm in the @drupal namespace.
