[ltac] Warning for deprecated `Add Setoid` and `Add Morphism` forms.
The manual has long stated that these forms are deprecated. We add a
warning for them, as indeed `Add Morphism` is an "proof evil" [*]
command, and we may want to remove it in the future.
We've also fixed the stdlib not to emit the warning.
