Replaces `trigger_error()` with `wp_trigger_error()`. The usage of `wp_trigger_error()` avoids generating `E_USER` family errors unless `WP_DEBUG` is on. In doing so, users should not see these messages in normal production. Notes: * Removes `E_USER_NOTICE` when passed as an argumnent, as it's the default error level. * An empty string is passed for the function name when its name is already in the error message or does not add value to the error message. * Externally maintained libraries are not included. Follow-up to [55204], [25956], [29630], [38883], [52062], [52049], [54272], [38883], [55245], [51599], [14452], [38883], [24976]. Props prasadkarmalkar, rajinsharwar, thelovekesh, hellofromTonya, swissspidy. Fixes #59652.
