Subject: [PATCH 1/2] Add missing AppIcon.ico entry to SingleProjectPackagedApp
 vstemplate

The .vstemplate was missing the AppIcon.ico ProjectItem in its Assets
folder, so Visual Studio never copied the icon into new projects created
from this template, causing APPX0702 build errors.

Subject: [PATCH 2/2] Add missing AppIcon.ico entry to BlankApp (wapproj)
 vstemplate

Same issue as SingleProjectPackagedApp: the .vstemplate was missing the
AppIcon.ico ProjectItem, so Visual Studio never copied the icon into new
projects created from this template, causing APPX0702 build errors.
