[feature suggestion]: Build for Web and Mobile

Currently the plugin is aimed towards mobile only. Its nx serve command is running tns.

This doesn't support architectures like this code sharing.

I know that NS is not just for angular, but this might be super useful in case one chooses an angular NS project.

One idea would be to enable several such features:

1. Allow to serve regular apps vs NS (e.g. via a flag)
2. Allow to create duplicate modules/components/etc. files (both .tns and web) like suggested in the article

I haven't made the attempt to make the separation but there should be more features involved in this Epic.

Commencez par retracer le point d’entrée nx serve du plugin et la manière dont il invoque actuellement tns. Définissez le périmètre du service des applications web classiques par rapport aux applications NativeScript, ainsi que de la génération de fichiers .tns et web associés, puis vérifiez le comportement convenu avec des tests appropriés.
