Summary:
Fixes T13265. See that task for discussion. Briefly:
- For mailers that use other mailers (SMTP, Sendmail), optionally let administrators set `"message-id": false` to improve threading behavior if their local Postfix is ultimately sending through SES or some other mailer which will replace the "Message-ID" header.
Also:
- Postmark is currently marked as supporting "Message-ID", but it does not actually support "Message-ID" on `secure.phabricator.com` (mail arrives with a non-Phabricator message ID). I suspect this was just an oversight in building or refactoring the adapter; correct it.
- Remove the "encoding" parameter from "sendmail". It think this was just missed in the cleanup a couple months ago; it is no longer used or documented.
Test Plan: Added and ran unit tests. (These feel like overkill, but this is super hard to test on real code.) See T13265 for evidence that this overall approach improves behavior.

Summary:
Ref T920. Ref T12404.
- Update to the new "$message" API.
- Remove "encoding". I believe "base64" is always the best value for this since we stopped seeing issues once we changed the default.
- Remove "mailer". This is a legacy option that makes little sense given how configuration now works.
- Rename to "SMTP". This doesn't affect users anymore since this mailer has been configured as `smtp` for about a year.
- This does NOT add a timeout since the SMTP code is inside PHPMailer (see T12404).
Test Plan: Sent messages with many mail features via GMail SMTP and SendGrid SMTP.
