This is a maintenance and feature release, adding support for the official release of PHP 8.3, methods for removing and replacing custom headers, XCLIENT support, and links to a new way of implementing XOAUTH2 authentication.
The only change likely to have any impact on existing code is that PHPMailer previously attempted to use opportunistic STARTTLS encryption when connecting to `localhost`, which was unlikely to work. The workaround required setting `SMTPAutoTLS = false`, but that's no longer required. You may still need to use this setting when connecting to literal IPs.

This is a maintenance release with a new feature: DSN URL parsing, which allows you to create a PHPMailer instance with most important settings by passing in a single URL, ideal for configuring PHPMailer from an environment variable.
Note: This commit does not include new DSN class, as it is not particularly relevant for WordPress core at this time.

This is a minor feature release.
> Prior to this version, any OAuth provider needed to extend the provided `OAuth` base class, and this made it difficult to use with libraries other than ones based on the default [https://github.com/thephpleague/oauth2-client league] client packages. The OAuth property now accepts anything that implements the `OAuthProviderInterface`, making it much easier to use things like [https://github.com/googleapis/google-api-php-client Google's own OAuth classes]. Existing implementations that extend the provided `OAuth` base class will still work, as that base class now implements this interface too.
>
> When TLS errors occurred in PHPMailer, the error messages were often missing important info that might help diagnose/solve the problem. These error messages should now be more informative. A minor change is that a TLS error on SMTP connect will now throw an exception if exceptions are enabled.

This is a maintenance release. Changes include:
* Handle early connection errors such as 421 during connection and EHLO states.
* Make the `mail()` and sendmail transports set the envelope sender the same way as SMTP does, i.e. use whatever `From` is set to, only falling back to the `sendmail_from` php.ini setting if `From` is unset. This avoids errors from the `mail()` function if `Sender` is not set explicitly and php.ini is not configured. This is a minor functionality change, so bumps the minor version number.
* Extend `parseAddresses` to decode encoded names.

Now that WordPress Core supports PHP >= 5.6, the PHPMailer library can be updated to the latest version.
The PHPMailer files now reside in a new directory, `wp-includes/PHPMailer`. These files are copied verbatim from the library upstream and will make updating in the future easier. For backwards compatibility, the old files will remain and trigger deprecated file warnings.
The PHPMailer class is also now under the `PHPMailer\PHPMailer\PHPMailer` namespace. The `PHPMailer` class in the global namespace has been aliased for a seamless transition.
This upgrade also clears up a handful of PHP compatibility issues detailed in #49922.
