 Default `$parent` in `category_exists()` should default to null rather
 than 0.

 [29863] made the corresponding change in `term_exists()`. Failure to
 change the
 default value in `category_exists()` meant that an unspecified value for
 `$parent` would limit results to top-level categories.

 Includes unit tests and corrected function documentation.

 Props hissy.
 Fixes #30975 for trunk.
