Remove standalone ArrayWrappers tests - functionality tested in conversion provider

Removed test_array_wrappers.py and test_files/array_wrappers/ directory since:
- ArrayWrappers are now inlined into generated modules (not standalone)
- Functionality is already tested in test_numpy_vector_converter.py
- 13 tests were skipped and redundant with existing integration tests

All ArrayWrapper/ArrayView functionality is validated through the conversion provider tests which exercise the actual use case.
