feat(@schematics/angular): enable routing by default for new applications

This commits updates the `routing` option in the `ng new` and `ng generation application` schematics to `true` by default and also removed the `Would you like to add Angular routing?` prompt.

BREAKING CHANGE: Routing is enabled by default for new applications when using `ng generate application` and `ng new`. The `--no-routing` command line option can be used to disable this behaviour.
