Fixes#19887.
This PR fixes several Relax TensorRT BYOC issues exposed by YOLO-style
models:
- adds TensorRT support for SiLU and resize2d
- preserves operand and TupleGetItem ordering during codegen
- fixes cyclic and unsafe Tuple/TGI region merging
- handles static Shape bindings and nested packed-function outputs
- normalizes PrimType dtype arguments passed to relax.arange
With these changes, yolo11n-seg can be merged into a single TensorRT
region, while yolo11n can be imported and partitioned successfully.
