Rebootstrap SB SDK/artifacts

[mthalman]

This is necessary in order to get a new SDK with a fixed version of the crossgen2 tool for resolving dotnet/source-build#4007

[mthalman]

Dealing with some incoherency issues here, I think.

First commit:

    /vmr/src/aspnetcore/src/Mvc/Mvc.Api.Analyzers/src/Microsoft.AspNetCore.Mvc.Api.Analyzers.csproj : error NU1605: Warning As Error: Detected package downgrade: System.Collections.Immutable from 9.0.0-preview.2.24123.1 to 9.0.0-preview.2.24122.4.

The failures in the unified-build pipeline are caused by #18768

@KevinRansom - Can you take a look at these F# failures that are occurring in the VMR build (specifically the installer-source-build pipeline)? The changes that are being made here are to update the SDK version that is used by the build. That's running into a bunch of these FS1118 errors:

##[error]/vmr/src/fsharp/src/FSharp.Core/array.fs(2297,17): error FS1118: Failed to inline the value 'groupByImplParallel' marked 'inline', perhaps because a recursive value was marked 'inline' [/vmr/src/fsharp/src/FSharp.Core/FSharp.Core.fsproj::TargetFramework=netstandard2.1]

Do your recent changes in dotnet/fsharp#15484 potentially resolve this? Those changes haven't flowed into installer yet. Or otherwise, do you know what should be done to fix this?

[mthalman]

The unified-build pipeline is running into the same error as dotnet/sdk#39050 (comment) which was fixed there. Merging in latest to get that fix.

Errors in aspnetcore for installer-source-build:

/vmr/src/aspnetcore/src/Analyzers/Analyzers/src/Microsoft.AspNetCore.Analyzers.csproj(0,0): error NU1605: (NETCORE_ENGINEERING_TELEMETRY=Restore) Warning As Error: Detected package downgrade: System.Collections.Immutable from 9.0.0-preview.3.24154.10 to 9.0.0-preview.2.24128.5. Reference the package directly from the project to select a different version. 
 Microsoft.AspNetCore.Analyzers -> Microsoft.CodeAnalysis.CSharp 4.10.0-3.24151.8 -> Microsoft.CodeAnalysis.Common 4.10.0-3.24151.8 -> System.Collections.Immutable (>= 9.0.0-preview.3.24154.10) 
 Microsoft.AspNetCore.Analyzers -> Microsoft.CodeAnalysis.CSharp 4.10.0-3.24151.8 -> System.Collections.Immutable (>= 9.0.0-preview.2.24128.5)

Pretty sure this is because the Roslyn version is the same between the preview.2 source built artifacts being used to bootstrap with and the version of Roslyn that's currently being built in the VMR. It causes non-determinism on which package gets used by source build.

Waiting on #18875 to be merged which will upgrade the Roslyn version so that it won't conflict.

Doesn't the Arcade Sdk entry in global.json need to be updated as well?

Getting a whole bunch of test failures when attempting to run dotnet build in the tests:
