trunk/541177649c3ba95ff4999644eb20c9813ec7f153: Add boundary checks in set_storage_quantized_ (#184561)

set_storage_quantized assigns storage, offset, sizes and strides directly without validating that they fit the storage. Route through checkSetStorage/checkInBoundsForStorage so the quantized path matches the validation set_ already performs.

Tighten _rebuild_qtensor's per_channel branch: the C++ quantizer constructor does not bound-check axis against len(size) nor scales/zero_points length against size[axis], so validate both before constructing the tensor.

Adds test_weights_only_rebuild_qtensor_bounds covering both the rebuild_qtensor entry point and a direct q_tensor.set(...) call.

Authored with Claude.
