[PTen] Add cmake function for kernels
添加cmake函数register_kernels，类似原先的register_operators，扫描目录下所有kernel实现，根据文件名创建编译target，同时解析kernel注册代码，在公共头文件中添加kernel符号导出的声明，要求kernel按如下形式组织：
***_kernel.h，有其他kernel复用当前kernel时，需在相应.cc/cu中include复用kernel的头文件cpu/***_kernel.cc此PR合入后，无特殊情况，不需要额外添加cmake条目与kernel declare声明，暂时如果依赖关系比较特殊的话，还需要手动声明一下，例如
kernel_library(flatten_kernel DEPS ${FLATTEN_DEPS})TODO：自动根据头文件include关系，自动生成kernel复用时的编译依赖关系
