soc/intel/common/cse: Add consistent HECI command id/group id naming
Below changes are done:
1. Consistent HECI command/group ID naming.
2. Rename macros to match with Intel ME BIOS Spec.
3. Move command ids, group ids and related macros into cse.h
4. Add description for structure members.
TEST=Build and Boot hatch board.
