Run libtests in interpmode1 so it is faster (#127076)

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
