 Mail: Improve handling of UTF-8 address headers.

 Previously, `wp_mail()` implemented Reply-To as a generic header, using
 PHPMailer's `addCustomHeader()`. As such, the email address portion of
 the header was being incorrectly encoded when the name portion
 contained UTF-8 characters. Switching to PHPMailer's more specific
 `addReplyTo()` method fixes the issue.

 For greater readability, the handling of all address-related headers
 (To, CC, BCC, Reply-To) has been standardized.
