* Fix tests for AssemblyLoadContext isolation in .NET 10

- Add AssemblyLoadContext workaround for CSharpScript compatibility
- Update tests to verify execution success and return values instead of
  console output (Console.SetOut doesn't propagate across ALCs)
- Change timeout test to use Task.Delay which respects cancellation
- Minor cleanup in CSharpEvalTools (use CancelAsync)

See: dotnet/roslyn#45197 (comment)
