parse-options: remove OPT_BOOLEAN

After a86a8b9 (sb/parseopt-boolean-removal), the deprecated
OPT_BOOLEAN is not used anywhere except by OPT__* macros. Kill
OPT_BOOLEAN and make OPT__* use OPT_COUNTUP directly instead. This
should stop OPT_BOOLEAN from entering the tree again in new patches.

OPT__DRY_RUN() is converted to use OPT_BOOL though because it does not
make sense to increase the level of dryness. All OPT__DRY_RUN call
sites have been checked and they look safe for OPT_BOOL.
