Sergey Biryukov e2a5b8684e Coding Standards: Standardize on user_id when passing data to comment functions.
The `wp_new_comment()`, `wp_update_comment()`, and `wp_filter_comment()` functions already normalize the `user_ID` parameter internally to `user_id`, which matches the database field name.

This commit aims to bring some consistency when passing the parameter in core.

The corresponding `$user_ID` variable is also renamed to `$user_id` to match the other variables when not referring to the `$user_ID` global, which has an exception in the WordPress coding standards.
