ggml : always define ggml_fp16_t as uint16_t (llama/5666)
* ggml : always define ggml_fp16_t as uint16_t ggml-ci * ggml : cont ggml-ci * ggml : cont * ggml : cont ggml-ci * ggml : cont ggml-ci * cuda : no longer ggml headers last ggml-ci * ggml : fix q6_K FP16 -> FP32 conversion ggml-ci * ggml : more FP16 -> FP32 conversion fixes ggml-ci
