Fix finite_set sort cardinality computation for finite base sorts (#7997) 
* Initial plan

* Implement cardinality computation for finite_set sorts

- Modified mk_sort in finite_set_decl_plugin.cpp to compute 2^|s| for finite base sorts
- If base sort size > 30, mark finite_set sort as very_big
- Added comprehensive tests to verify sort size calculations
- All tests pass successfully

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

* Update finite_set_decl_plugin.cpp

* Fix unit tests for infinite base sorts

Updated test to check is_infinite() instead of is_very_big() for FiniteSet(Int) since infinite element sorts now result in infinite FiniteSet sorts (not very_big). Also updated comment to clarify the behavior.

43d40ac142 revise axiom instantiation scheme for finite-sets 
Instead of asserting theory axioms lazily we create them on the fly and allow propagation eagerly.
The approach uses a waterfall model as follows:
- terms are created: they are inserted into an index for (set.in x S) axiom creation.
- two terms are merged by an equality.
  Loop over all new opportunities for axiom instantiation
  New axioms are added to a queue of recently created axioms.
- an atomic formula was asserted by the SAT solver.
  Update the watch list to find new propagations.

During propagation recently created axioms are either inserted into a propagation queue, or inserted into a watch list.
They are inserted into a propagation queue all or all but one literal is assigned to false.
They are inserted into a watch list if at least two literals are unassigned
They are dropped if the axiom contains a literal that is assigned to true

The propagation queue is processed by by asserting the theory axiom to the core.

Also add some elementary statistics.

A breaking change is to change the datatype for undo-trail in smt_context to not use a custom data-structure.
This can likely cause regressions. For example, the region allocator now comes from the stack_trail instead of being
owned within smt_context with a different declaration order. smt_context could crash during destruction or maybe even pop.
We take the risk as the change is overdue.

Add swap method to ref_vector.
