1. Extract op info from AnfNode when generating composite operators.
2. Ignore the op register info when selecting kernel.
3. Update akg submodule.
4. Remove akg gpu op registers that added for GraphKernel.
5. Add an interface `IsNodeInGraphKernel` into `AnfRuntimeAlgorithm`, next to the `IsGraphKernel`.
6. Sort included fils for the clang-format rule is changed.

TODO: Remove the json generator in GraphKernelExpander, it's ok to call this interface.
