John Blackbourn 75d2020f3f Cron API: Introduce a $wp_error parameter to functions that write to the cron array. ...

This allows the functions to return a `WP_Error` object containing more information in case of a problem, instead of just boolean false.

The various `pre_` filters in these functions are also updated so they can return or be passed a `WP_Error` object.

Fixes #49961
