fix(angular): install @angular/cli if not installed

[leosvelperez]

Current Behavior

When adding the @nrwl/angular package to an empty workspace and generating a new Angular project, the @angular/cli package does not get installed. This can cause some issues with some tooling relying on it.

Expected Behavior

Creating a new Angular project should install @angular/cli if it is not installed.
