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.
