Pull Request Overview

This PR updates the codebase to eliminate automatic hipification of CUDA code by setting the default hipify parameter to False. The changes primarily involve replacing CUDA-specific headers and API calls with their HIP equivalents throughout the codebase, ensuring native HIP compatibility without relying on runtime code translation.

Key changes:

• Changed default hipify behavior from True to False in JIT compilation
• Replaced CUDA headers (ATen/cuda/*, c10/cuda/*) with HIP equivalents (ATen/hip/*)
• Updated CUDA stream and device guard APIs to use HIP-native implementations
• Replaced cudaStream_t and cudaEvent_t types with hipStream_t and hipEvent_t
