Add B3_PyArray_DATA macro that casts PyObject* to PyArrayObject* for NumPy 2.0+ where PyArray_DATA expects PyArrayObject*. Maintains backward compatibility with older NumPy versions. Fixes build errors on Ubuntu Resolute with NumPy 2.x where PyArray_DATA calls had incompatible pointer types.

merged #4787 into my branch, since it properly fixes the numpy related compile errors |

This function is useful in scenarios with larger numbers of rigidbodies ( > 500) in order to retrieve a numpy transforms array in one go. Querying all transforms in a frame loop in order to update a render representation, e.g. a shattered blender mesh one by one is a significant performance bottleneck.
Unfortunately, i had to deactivate 2 sections of different numpy related code via #if 0 due to compilation errors i couldnt easily fix. (I didnt change anything else of that code, I added only my C loop function)
If you may find this function useful, feel free to integrate it. Maybe i have overlooked a "Better" way tho, but this improved the performance significantly if you need to use a lot of transformation data.
