This PR depends on #647

[Copilot]

Pull request overview

This PR enables Epilogue Visitor Tree (EVT) Python unit tests for Intel XPU devices (PVC/Xe12 and BMG/Xe20) by adding device detection, platform-specific implementations, and adapting test infrastructure to work with both CUDA and SYCL backends.

Key changes:

• Add Intel Xe12 (PVC) and Xe20 (BMG) support to EVT backend with new node implementations and emitters
• Update device detection to differentiate between BMG (CC=20) and PVC (CC=12) Intel GPUs
• Modify test infrastructure to support XPU tensors and dynamic device selection (CUDA/XPU/CPU)

Mistakenly approved. Need explanation for the comments.

I believe it make sense to typdef instead of just using sm90 (it would avoid the confusion and will set direction to add support for future architecture. Okay to make the changes in next revision
