    [CALC] Use pragma once for calc.h (#5754)
    
    It's simpler and only needs to be included once at the beginning of the
    header file. It generates an unique identifier for the file automatically,
    so maintainers wouldn't need to choose unique names for the macros.
    It will be helpful if any future refactoring takes place.
