Implement inverter functions for finite-set operators (#7974) 
* Initial plan

* Add set operator inverters to array_expr_inverter

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

* Refactor expr_inverter to remove set operations

Removed handling for set operations like union, intersection, and difference in expr_inverter.cpp. Introduced finite_set_inverter class to manage set union operation.

* Remove OP_SET_COMPLEMENT case from expr_inverter

Removed handling for OP_SET_COMPLEMENT in expr_inverter.

* Change OP_SET_UNION to OP_FINITE_SET_UNION

1f8b08108c #7739 optimization 
add simplification rule for at(x, offset) = ""

Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions.
The example highlights some opportunities for simplification, noteworthy at(..) = "".
The example is solved in both versions after adding this simplification.
