kbuild: warn if FORCE is missing for if_changed(_dep,_rule) and filechk
if_changed, if_changed_dep, and if_changed_rule must have FORCE as a
prerequisite so the command line change is detected.
Documentation/kbuild/makefiles.rst clearly explains it:
Note: It is a typical mistake to forget the FORCE prerequisite.
However, not all people follow the document.
This mistake occurred again and again, so a compelling force is needed.
Show a warning if FORCE is missing in the prerequisite of if_changed
and friends. Same for filechk.
