The role of the `zify_saturate` tactic is to augment the goal with
positivity constraints.  The premisses were previously obtained from
the context. If they are not present, we instantiate the saturation
lemma anyway.

Also,
- Remove saturation rules for Z.mul, the reasoning is performed by lia/nia
- Run zify_saturate after zify_to_euclidean_division_equations
- Better lemma for Z.power
- Ensure that lemma are generated once

The vernacular command takes a reference instead of a constr.
Moreover, the head symbol is checked i.e
Add Zify InjTyp ref checks that the referenced term has type
Intyp X1 ... Xn
