Martin Kustermann c133aa8660 Reland "[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.

This is a unmodified reland of

  https://dart-review.googlesource.com/c/sdk/+/204500

after some remaining g3 usages have been fixed (the flutter
roll didn't port the GN changes to BUILD changes in g3)

TEST=Existing test suite.
