Fix for the issue where PT Run was preventing UWP apps from building in VS

[alekhyareddy28]

Summary of the Pull Request

• This PR ensures that PT Run does not deny UWP apps from being built in visual studio.
• There was another issue which had to be fixed to be able to reproduce the above error. As we have added the package wrapper for UWP applications, the exceptions are being thrown in the constructor and not all of them were being handled there. One such exception that was being thrown was the Argument Exception.
  
• Once the Argument exception was handled, this error was reproducable while building UWP apps.

Detailed Description of the Pull Request / Additional comments

• An Argument Exception was being thrown when when package.InstalledLocation.Path was being accessed. It threw a value is not found in the expected range exception.
• That exception is not of type ArgumentNullException or ArgumentOutOfRangeException so other than catching the exception, no other check could be performed.
• While reading the app manifest file, it was being read with deny_write STGM constant which prevented any other process from modifying it. This was causing all the appxmanifest.xml files to be locked by PowerToys run. Changing it to deny_none fixed this issue. Ref - https://docs.microsoft.com/en-us/windows/win32/stg/stgm-constants. We will not face an issue where we would try to read an incompletely installed packaged app because we proceed only if the installation is complete (using args.IsComplete).
• There was a similar issue while loading the img icon into a bitmap Image format. Once the image was loaded it could not be deleted, throwing this error -
  
• To fix this, instead of passing the uri directly, passing the file as a memory stream fixed the issue. Ref - https://stackoverflow.com/questions/542217/load-a-bitmapsource-and-save-using-the-same-name-in-wpf-ioexception.

Validation Steps Performed

• Manually validated that none of those errors are hit while building UWP apps.
