Description

I found a completely unused file:

• src\Xamarin.Android.Build.Tasks\MSBuild\Xamarin\Android\Xamarin.Android.Common\ImportAfter\Microsoft.Cpp.Android.targets

To see if a file is for sure unused, look at:

• build-tools\installers\create-installers.targets

Add a note to .github/copilot-instructions.md such as:
