MapFission transformation cannot handle strided or symbolic maps

**Describe the bug**
The MapFission transformation produces InvalidSDFGEdgeError: Memlet subset out-of-bounds on strided maps.

Additionally it raises StopIteration if the sdfg uses symbols.

**To Reproduce**
Run [reproduce.py](https://github.com/user-attachments/files/26720381/reproduce.py)
The testcases will print FAIL

**Expected behavior**
Testcases print PASS
which means that:
1. MapFission is applied
2. It validates without errors
3. It produces the same numeric result
