Fix: Add oryx to optional deps and patch ROCm resource leak

[Abinesh-Mathivanan]

I found these two issues while reading the repo,

1. The experimental fusion module relies on oryx, but it was not listed as a dependency. I've added it to pyproject.toml under a new [project.optional-dependencies.experimental] group to make the dependency explicit for users of this feature.
2. The compile_ttir_to_hsaco_inplace function created a temporary file for the HSACO binary but never deleted it. I have wrapped the kernel instantiation in a try...finally block to ensure os.remove() is called on the temporary file, preventing a resource leak.
