DRAFT: Beta Support for XDNA2 Platform

[Victor-Jung]

This PR adds beta support for the XDNA2 platform. This is also the first attempt at adding a new MLIR backend for Deeploy.

Currently, it passes a single Add node ONNX graph; on this platform, there is no such "untitled" execution possible, as the AIE cores can't read outside their local L1. Hence, the XDNA platform is inherently tiled.

Currently, the CI uses self-hosted runners to run directly on the XDNA2 NPU from a Minisforum X1 Pro.

Added

• A Dockerfile specifically for the XDNA platform. It only requires the 'mlir-aie' and 'llvm-aie' packages installable with pip. You have to run this container with specific arguments to forward the NPU device and driver libraries; the procedure is described in README_XDNA.md.
• A new target library for XDNA2. It uses the LLVM compile for AIE (named peano) to compile the add kernel.
