Style refactoring

[alecarn]

This is a big one, we refactored all the library style.

• No more magic import each file know what to do.
• Remove scss-bundle
• Refactor the pipeline and migrate gulp script to use the native ng-packagr capabilities or node
• Allow style composition
• Remove gulp fix for @angular/cdk styles

TO TEST THIS PR, YOU NEED TO:

1. Check this branch
2. Delete the node_modules folder or @angular and stylus folder (unwanted fix is apply to @angular and stylus library)
3. Launch a clean install "npm ci"

What is the current behavior? (You can also link to an open issue here)
All the prebuilt themes was bundled and loaded in each app

What is the new behavior?
Compile prebuilt themes seperately and load only the theme we need.
