Whisper.cpp support

Ryzen AI provides NPU acceleration for whisper.cpp through an AMD-maintained fork. On AMD Ryzen AI 300 Series systems, Whisper can fully offload the encoder to the NPU, which can deliver a significant speedup versus CPU-only runs. NPU acceleration is currently supported on Windows only, with Linux support planned.

For setup steps, build flags, and NPU-optimized model guidance, refer to the GitHub README at amd/whisper.cpp
