Remove CUDA_STATIC_RUNTIME option, always use static linking

- Remove CUDA_STATIC_RUNTIME option from cpp/CMakeLists.txt
- Always use static CUDA runtime in rapids_cuda_init_runtime
- Update get_cutlass.cmake and get_faiss.cmake to always use static
- Remove CUDA_STATIC_RUNTIME from python/libcuvs/CMakeLists.txt
- Remove CUDA_STATIC_RUNTIME from docs
- Remove cuda-cudart from run requirements in conda recipes
