Revert "[vm] Remove --causal-async-stacks flag"

This reverts commit b1f1aee94d8730d7d3b6def8a1fffec2181fcfb1.

Reason for revert: Some left-over uses in g3 need to removed first
(some were removed in b/380758599 but apparently there's some
usages left).

Original change's description:
> [vm] Remove --causal-async-stacks flag
> The flag isn't used anywhere in our tests or in embedder code. Turning
> it on will result in a VM startup error.
> We should therefore remove all uses of the flag and the flag itself.
> TEST=Existing test suite.
