refactor(schematics): foundation for cdk schematics (#13213)

* Moves the utility functions which will be needed for building CDK schematics to the CDK (`cdk/schematics`).
* Updates package tools to properly build schematics for CDK and Material (shared logic for building schematics; Material schematics depend on CDK schematics)
* Update to `ng-add`: The Angular CLI only installs `@angular/material` if someone runs `ng add @angular/material`. But since we need access to the utility functions from the CDK, we need to install the dependencies first, and then setup the project.
