Replacement for Microsoft.CodeAnalysis.Build.Tasks package

[rainersigwald]

It looks like after #78584 the Microsoft.CodeAnalysis.Build.Tasks package isn't getting published, which is breaking the MSBuild repo's use of it (to construct a more-up-to-date-than-the-LKG output directory using a newish Roslyn). That's causing dotnet/msbuild#11877 to fail to restore.

Is there a replacement we can reference instead? None of the packages published in recent builds jump out at me.

We removed the publishing for that package because it hadn't been updated in ~4 years on nuget.org. Didn't realize it was being published internally.

Do you just need the layout of the directory as it will exist in Visual Studio?

[rainersigwald]

Ideally, yes--we use it when we're assembling our bootstrapped MSBuild. But if it's hard to get that, we can probably just go to "the Roslyn we just built ourselves with".

The build/tasks/net472 directory of Microsoft.Net.Compilers.Toolset has the layout for we generate for VS MSBuild in the Roslyn directory.
