[DO NOT MERGE] Add AppExecutionAlias extension to the app for cmdline launch

[radujipa]

The extensions registers an executable alias for the UWP app which
can be used from Powershell or Command Prompt to launch the app.
Additional support can be made in order to interpret command line
parameters when launching the app. This may be useful for debugging
and development.

Note:

Used this article for reference. Also tried the extension to Kano Hub and was able to launch it simply from Powershell.

As an alternative, I was able to launch the Star Wars app from Powershell with the following but it was not clear that additional arguments could be specified:

start shell:AppsFolder\KanoComputing.StarWarsCodingKitbyKano_8bypc573fhhxp!KanoComputing.StarWarsCodingKitbyKano

However, as mentioned in the article, the arguments need to be handled and if it does work, the app might open with a blank page.

@rachaelcodes Let's build this and test with your app and see how it reacts to the args you were trying to pass to it.

hm I can't see this module referred to in kit-app-ui, unless I'm missing something? It looks like the builds come from the windows-store module instead
