feat(@angular-devkit/build-angular): support keyboard command shortcuts in application dev server

When using the `application` or `browser-esbuild` builders with the `dev-server`, interactive key
shortcuts are now available to use while the server is active. Once the build has successfully completed
and the development server has initialized, typing a single letter key followed by enter will execute
the associated action. These actions include forcing a browser full reload, clearing the console, or
quitting. More actions may be added in the future.

The following actions are currently available:
```
  press r + enter to force reload browser
  press u + enter to show server url
  press o + enter to open in browser
  press c + enter to clear console
  press q + enter to quit
```

The `h` action is also available which will display the above list at runtime.
