Revert "Revert commit" - Using centralized package management for vcxproj (#44289)

Reverts microsoft/PowerToys#44208
Basically enable back: https://github.com/microsoft/PowerToys/pull/43920

the core change is adding this new Target to ensure when "building in
Visual Studio", it will restore the nuget package first for vcxproj:
```xml
  <!-- Auto-restore NuGet for native vcxproj (PackageReference) when building inside VS -->
  <Target Name="EnsureNuGetRestoreForVcxproj" BeforeTargets="PrepareForBuild" Condition="
            '$(BuildingInsideVisualStudio)' == 'true'
            and '$(DesignTimeBuild)' != 'true'
            and '$(RestoreInProgress)' != 'true'
            and '$(MSBuildProjectExtension)' == '.vcxproj'
            and '$(RestoreProjectStyle)' == 'PackageReference'
            and '$(MSBuildProjectExtensionsPath)' != ''
            and !Exists('$(MSBuildProjectExtensionsPath)project.assets.json')
          ">

    <Message Importance="normal" Text="NuGet assets missing for $(MSBuildProjectName); running Restore...; IntDir=$(IntDir); BaseIntermediateOutputPath=$(BaseIntermediateOutputPath)" />

    <MSBuild Projects="$(MSBuildProjectFullPath)" Targets="Restore" Properties="RestoreInProgress=true" BuildInParallel="false" />
  </Target>
```
