Run libtests in interpmode1 so it is faster

[BrzVlad]

Remove windows runs from the pipeline. Many suites fail with com related tests and windows is not really relevant as a target for now. We still run full runtime tests on windows.

STJ.Tests

• jit 2min
• interpmode1 15min
• interpmode3 >1.5h

This also uncovers a new set of failures that we will need to address

Pull request overview

Adjusts interpreter library test execution (scenario + pipeline coverage) and fixes a GC safety issue in interpreter async continuation resumption.

Changes:

• Switches the libraries interpreter Helix scenario from interpmode3 to interpmode1 and updates the associated work item timeout.
• Updates the libraries-interpreter.yml pipeline to stop scheduling windows_x64 and to run interpmode1.
• Adds GC interior-pointer protection for resultStorage during AsyncHelpers_ResumeInterpreterContinuationWorker execution.
