add all missing constraint for HFmodel (#81714)
- Modify "view" function to infer only concrete dimensions instead of Dyn, to allow us to prove conditionals without any additional constraints
- Complete the missing constraints for an HF model to work (mostly equality constraints of the form input = output)
- Implement inequality.
