Changing `Q(A) & Q(B)` to `Q(B) & Q(A)` (or `Q(B, A)`) generates a
migration that drops and recreates the exact same constraint.
Suggesting to build on the work in #34744 to adjust the identity property
for Q objects to use a deterministic sort, given that `^`, `&`, and `|`
operations are commutative.
