[NB] resizable components backbone (#12936)

* [NB] resizable components backbone

 - create backend data type for resizable components
 - fully independent for-loops (they can be solved in any order) are detected
   ToDo: detect forward or reverse forced for-loops as well
   ToDo: allow certain slicing if its recoverable as for-loop
 - create algorithm code for now
   ToDo: make it actually resizable

* [testsuite] add test case from open scaling

* [NB] save solved resizable equation

* [NB] fix if-equation toStatement

 - IF: replace END condition with BOOLEAN(true) (thats what the frontend wants)
 - Types: don't use array element types rather use the original ones

* [testsuite] update for resizable components
