This removes the WAP project Files.Package.wapproj and moves assets and the appx manifest to the entry point project Files.App.

• Move assets & Package.appxmanifest to Files.App
• Add launchSettings.json
• Update build properties in Files.App
• Update CI
• Update CDs

Steps used to test these changes

1. Restore Files

   cd D:\Source\Files\src\Files.App
   msbuild ../../Files.slnx /t:Restore /p:Platform=x64 /p:Configuration=Release
   

2. Build and package

   msbuild Files.App.csproj /p:Platform=x64 /p:Configuration=Release /p:AppxPackageDir=D:\Source\Files\artifacts\
   

3. Check if the generated msixbundle contains msix files for x64 and arm64 (unzip it to see files inside)
   
4. Check if each msix contains the appropriate 7z binary (unzip it to see files inside)
