suggest CAllGatherOpASCENDKernel -> AllGatherOpNPUKernel, removed prefix "C" since it looks like word "CAll".

We‘d better keep this style, because other ops under this path start with 'C'. Maybe it means these ops were implented by c/c++ language.

Maybe add a new line after the last line and the symbol will dismiss.

Is const_cast necessary?

just delete it

we need it somewhere, but we do not need it for most time, I have delete most of unneeded case.
