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.

d6908a3d4b support AC parsing 
By tagging union and intersection as AC we allow parsing set union and intersection as n-ary functions.
The internal representation remains binary.
