GPU: NVIDIA GeForce RTX 5070 Laptop GPU (sm_120, Blackwell) OS: Windows 11 Error: CUDA error: no kernel image is available for execution on the device

WhisperX/ctranslate2 is compiled for sm_70-sm_90 but RTX 5070 Laptop requires sm_120.

Please update ctranslate2 to support Blackwell architecture (sm_120).
