Make sure the individual getter/setter workaround for structs in NNBD
works. That way structs can be migrated without having to opt in to
the proposed --enable-experiment=external-abstract-variables for
external fields.
Note that this requires dart:ffi users to migrate twice for NNBD, once
to the workaround, and later a cleanup to external fields.
