fix: do not request ALPN on standard ports and when using STARTTLS
...
Apparently some providers fail TLS connection
with "no_application_protocol" alert
even when requesting "imap" protocol for IMAP connection
and "smtp" protocol for SMTP connection.
Fixes <https://github.com/deltachat/deltachat-core-rust/issues/5892 >.

refactor: pass single ALPN around instead of ALPN list
...
This way there is always exactly one ALPN ("imap" or "smtp").

feat: set imap ALPN when connecting to IMAP servers
...
IMAP has a registered protocol ID
listed at <https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtml#alpn-protocol-ids >
Requesting specific ALPN on the client
should allow the server to
multiplex multiple protocols on the same
port and dispatch
requests to the correct backend on the proxy such as HAProxy.
