[ComfyUI-Windows] Add gfx1150 ROCm nightly index URL for Strix/Gorgon Point Ryzen AI APUs

[NeuralFault]

Adds support for GPU detection and Pytorch index-url support for TheRock nightlies for the Strix Point and Gorgon Point GPUs in the Ryzen AI 300/400 series APUs for ComfyUI installation in Windows.

GPU architecture support:

• Added handling for the gfx1150 architecture, mapping it to the https://rocm.nightlies.amd.com/v2-staging/gfx1150 index URL to support Strix/Gorgon Point GPUs.
• Added clarifying comments for both gfx1150 (Strix/Gorgon Point) and gfx1151 (Strix Halo) to improve maintainability and clarity.

The index used is V2-staging but was informed that the PyTorch functionality is stable and that there is no tester hardware for the TheRock CI for it to pass their PyTorch tests and be promoted to V2 index of the repo.

Thanks to a ROCm/TheRock contributor astrelsky for bringing it to my attention and informing on it's stability.

Code Review

This pull request correctly adds support for the gfx1150 architecture (Strix/Gorgon Point APUs) for ROCm on Windows by providing the appropriate nightly build URL. The added comments for both gfx1150 and gfx1151 improve code clarity. I have one suggestion to improve maintainability by using constants for the URLs.
