kbuild: refactor cc-option-yn, cc-disable-warning, rust-option-yn macros
cc-option-yn and cc-disable-warning duplicate the compile command seen
a few lines above. These can be defined based on cc-option.
I also refactored rustc-option-yn in the same way, although there are
currently no users of it.
