'dotnet store' can't find crossgen with .NET 6

Describe the bug

Calling ‘dotnet store’ on a package store manifest throws error that it can’t find crossgen, since crossgen is not included in the tools directory of .NET 6.0.3

To Reproduce

1. On Windows, install .NET 6.0.3 SDK
2. Create a file called packages.csproj
3. Fill it with the example content from here (the example with Moq and Newtonsoft.Json): https://docs.microsoft.com/en-us/dotnet/core/deploying/runtime-store
4. From the same directory as the created csproj run dotnet store --manifest packages.csproj --framework net6.0 --runtime win-x64
5. Exception is thrown
6. Add flag --skip-optimization to command and it will work

Exceptions (if any)

C:\Program Files\dotnet\sdk\6.0.201\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.CrossGen.targets(82,5): error NETSDK1016: Unable to find resolved path for 'C:\Users\username\.nuget\packages\microsoft.netcore.app.runtime.win-x64\6.0.3\runtimes\win-x64\native\..\..\..\tools\crossgen.exe'. [C:\Users\username\Downloads\DleteMe\subTest\testProject\packages.csproj]

@baronfel do you have a link to documentation for the mentioned FrameworkReference? A quick search only seems to show how to use the ASP.NET FrameworkReference, but in this case we’re trying to build our own custom store (maybe that means we should be trying to build our own custom FrameworkReference now?).

Our use case is shown here in the Lambda Layers CLI PublishLayers command.

I wrote this brain-dump on shared libraries last summer: https://github.com/dotnet/designs/blob/shared-libraries/accepted/2021/shared-libraries.md. It’s just a branch I pushed. Nothing more has happened on it. I didn’t even re-read it just now so I hope it is semi-coherent.

I’ll let @baronfel speak to the current status dotnet store.
