[9.0] Source-build issue in stage 2 build

[NikolaMilosavljevic]

Originally created in source-build repo: dotnet/source-build#4641

Stage 2 build is failing in vstest with the following error:

    /vmr/src/vstest/src/Microsoft.TestPlatform.PlatformAbstractions/common/Tracing/PlatformEqtTrace.cs(87,5): error IDE0032: Use auto property (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/style-rules/ide0032) [/vmr/src/vstest/src/Microsoft.TestPlatform.PlatformAbstractions/Microsoft.TestPlatform.PlatformAbstractions.csproj::TargetFramework=net9.0]

Test build (internal link): https://dev.azure.com/dnceng/internal/_build/results?buildId=2550295&view=logs&j=3121c41d-6088-53a5-4ef6-9a86f3460fe9&t=334539f4-dcef-5cad-a240-02997b3146e7

This can be reproduced in vstest repo builds by updating SDK to the latest 9.0 build.

There's another vstest issue: https://dev.azure.com/dnceng/internal/_build/results?buildId=2551180&view=logs&j=3121c41d-6088-53a5-4ef6-9a86f3460fe9&t=334539f4-dcef-5cad-a240-02997b3146e7

    /vmr/src/vstest/src/Microsoft.TestPlatform.CoreUtilities/Output/ConsoleOutput.cs(15,5): error IDE0032: Use auto property (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/style-rules/ide0032) [/vmr/src/vstest/src/Microsoft.TestPlatform.CoreUtilities/Microsoft.TestPlatform.CoreUtilities.csproj::TargetFramework=net9.0]

I'm not sure why the build is only reporting some of them at the time.
