6d5f050ed1 Convert internal class enums to enum class for type safety (#8158) 
* Initial plan

* Convert plain enums to enum class in EUF module

- Convert eq_status in euf::ac_plugin to enum class
- Convert undo_kind in euf::ac_plugin to enum class
- Convert undo_t in euf::arith_plugin to enum class
- Convert to_merge_t in euf::egraph to enum class
- Update all usage sites to use scoped enum syntax

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Convert more plain enums to enum class

- Convert state enum in substitution class
- Convert instruction enum in generic_model_converter class
- Convert eq_type enum in bit2int class
- Update all usage sites to use scoped enum syntax

4ef799ada4 fix #8109 
default behavior is conservative: if the body of a recursive function contains uninterpreted variables they are not rewritten.
Model evaluation will bind values to uninterpreted variables so the filter should not apply here.
