Support bang c kernel wanghailu 0927 (#43)

* fix a little bug which found by new verison CMake * add code for support BangC language kernel , just like Cuda kernel, not library * add bangc kernel * support BangC kernel * add code for support BangC kernel * support bangc kernel * fix some code from reviewer * fix code of template fumction * add code for support bangc kernel * fix bangc format Co-authored-by: wanghailu <wanghailu@qiyuanlab.com> Co-authored-by: Haojie Wang <haojie0429@gmail.com>
