  • This was causing real C# applications to fail to behave correctly on NativeAOT builds
  • Enable testing for covariant byref returns on nativeaot (split testing up so that the tests do not expect TypeLoadException, which NativeAOT doesn't reliably generate)
  • Put copy of attributetesting.il test into the managed type system unit test suite
  • Add regression test of issue noted in [NativeAOT] Method overrides with covariant return type don't work in all cases #96175 into managed type system unit test suite
  • Update workflow documentation to include a better path to finding details on how to run CoreCLR and Libraries tests for Native AOT

Fixes #96175
Fixes dotnet/runtimelab#205
