Description
The current implementation for `onnx.Loop` operator (PR #3408) does not support scan outputs. These are additional outputs that are concatenated across all iterations (see [operator spec](https://onnx.ai/onnx/operators/onnx__Loop.html) for more information).

Research direction
Start with the onnx.Loop implementation introduced by PR #3408 and read the linked ONNX operator specification, focusing on scan outputs. Trace the existing handling of Loop outputs and identify the relevant tests or entry points before making changes. Done means scan outputs are concatenated across all iterations and covered by tests.
