Re-enable C++/CLI tests

[wli3]

C++ does not support package restore. So, it is cannot download apphost pack from the internet. Since I made a change recently to use stage 2 bundled version props file instead of stage 0 (to avoid needing to update stage 0 when runtime insert), apphost will not be in the "dotnet" folder. The solution could be, in the test set up, download the missing apphost pack. But that will duplicate a lot of dotnet/installer code. Or move these tests to dotnet/installer.

Or overriding the implicit versions during the test themselves

Why not use PackageDownload?

[wli3]

C++/CLI project system does not support PackageDownload. And PackageDownload uses nuget

Fixed using the new package reference support!

There are 3 tests, It_can_generate_correct_depsJson_file, It_can_generate_all_runtimeconfig_files_to_output_folder, It_can_generate_all_depsjson_files_to_output_folder, that were all skipped for the predecessor to this issue. When running those tests, they all fail for the same reason:

C:\h\w\BA370A1F\p\d\sdk\9.0.100-ci\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(157,5): error NETSDK1145: The Apphost pack is not installed and NuGet package restore is not supported. Upgrade Visual Studio, remove global.json if it specifies a certain SDK version, and uninstall the newer SDK. For more options visit   https://aka.ms/targeting-apphost-pack-missing  Pack Type:Apphost, Pack directory: C:\h\w\BA370A1F\p\d\packs\Micros

(The text in the AzDO logs got cut off there, but you get the gist.) I'm reopening this issue and marking those tests as skipped by this issue.

@v-wuzhai can you take a look in your current pass over broken and skipped tests? I think we should be able to enable packagereference like the other c++ CLI tests and it'll download the apphost it needs.

I will try to enable EnableManagedPackageReferenceSupport to address the pass over broken and skipped tests.
