This commit fixes the arguments of the generated SDFG by the `dace_it…

…erator` and related problems.

GT4Py started to exhibit an issue (out of bounds access) with the introduction of [PR1457](spcl/dace#1457).
The commit fixes this, by creating the proper arguments and ensuring that the memory it operates on is continuous and proper allocated.
