parse-options: simplify usage argh handling

Browse Source 
Simplify the argh printing by simply calling usage_argh() if the option
can take an argument. Update macros defined in parse-options.h to set
the PARSE_OPT_NOARG flag.

The only other user of custom non-argument taking options is git-apply
(in this case OPTION_BOOLEAN for deprecated options). Update it to set
the PARSE_OPT_NOARG flag.

Thanks to Ren辿 Scharfe for the suggestion and starter patch.
