[vm] Rename tests causal_stacks -> awaiter_stacks and improve harness.

Browse source 
The main difference from the previous harness is that it
allows auto updating the expectations instead of
maintaining them manually.

This relands 0c1b2722ed with
changes to harness which fix issues on Windows.

Note: some amount of AOT failures are expected and should just
be approved. They will be fixed with the last CL in the series.
