Non-incremental build since .NET 11

[jjonescz]

1. Clone https://github.com/jjonescz/MsTestNonIncremental (a simple MSTest project, referencing a class library, using artifacts layout)
2. Run dotnet build -bl && dotnet build -question -bl:question.binlog
3. In .NET 10, that would succeed.
4. In .NET 11, that fails with: .nuget\packages\microsoft.testing.extensions.codecoverage\18.4.1\buildMultiTargeting\Microsoft.Testing.Extensions.CodeCoverage.targets(32,5): error MSB3492: Could not read existing file "artifacts\bin\MSTest\debug\.msCoverageExtensionSourceRootsMapping_MSTest" to determine whether its contents are up to date. Overwriting it.

Thanks for reporting this. This has been fixed and should be available in 18.5.x version.
