msix: modernize metadata #231
Description
Microsoft now recommends uap10:RuntimeBehavior and uap10:TrustLevel instead of EntryPoint, for modern applications.
If your package installs on systems older than Windows 10, version 2004 (10.0; Build 19041), then use the EntryPoint attribute instead of uap10:RuntimeBehavior and uap10:TrustLevel.
