 Mail: PHPMailer swap to use is_email for the default validator.

 Prior to the PHPMailer update in 5.5, old version of the PHPMailer was
 setting the validator to 'auto' resulting in a sophisticated logic for
 determining what email address validation should be used. But the new
 version defaults to 'php', possibly leading to rejection of email
 addresses which were fine prior to the upgrade. Let's use the WordPress
 core function `is_email()` so that it can be fully pluggable.

 Fixes #50720.
