* [CANN] Add Ascend NPU backend Ascend is a full-stack AI computing infrastructure for industry applications and services based on Huawei Ascend processors and software. CANN (Compute Architecture of Neural Networks), developped by Huawei, is a heterogeneous computing architecture for AI. Co-authored-by: wangshuai09 <391746016@qq.com> * delete trailing whitespaces * Modify the code based on review comment * Rename LLAMA_CANN to GGML_CANN * Make ggml-common.h private * add ggml_cann prefix for acl funcs * Add logging for CANN backend * Delete Trailing whitespace --------- Co-authored-by: wangshuai09 <391746016@qq.com>
