- A ParamResolver resolves variables into values. - Having non-trivial formulas as keys allows a significant complexity and ambiguity into ParamResolvers, since it is unclear how much is supported. Prevent this case altogether by raising an error if non-symbol formulas are used in ParamResolvers. Fixes: quantumlib#3550

Hey, I remember writing this issue!
Approved, but marked as BREAKING_CHANGE since this does cut some (possibly unintended) functionality of ParamResolver.
