Add support to invoke the application from command line

[harvinders]

Is your feature request related to a problem? Please describe.

It is currently not possible to invoke the application from command line. This removes one option to start the application for the user. It also makes it bit tricky to test the application if a tester wants to use the Process class to start the application. Test automation writers have to depend on shell to start the application.

Describe the solution you'd like

Use execution alias to add this capability. See here for details, https://blogs.windows.com/windowsdeveloper/2017/07/05/command-line-activation-universal-windows-apps/

Describe alternatives you've considered
