feat: add angular-devkit

[edusperoni]

This PR adds the angular devkit with brand new generators for component/pipe/directive.

This is still a draft as we need a few extra things (list is incomplete, will add more as needed)

• [ ] Integration with the angular cli so users don't need Nx

Main difference from the default nx generators is we add NO_ERRORS_SCHEMA and import NativeScriptCommonModule for standalone components
