[18.0][ADD] helpdesk_mgmt_mail_autogenerated_header

[jans23]

When a helpdesk ticket is created from an auto-generated email (e.g. an
out-of-office reply carrying Auto-Submitted: auto-replied or
X-Auto-Response-Suppress: AutoReply/All), the stage welcome email
configured on the ticket stage must not be sent back to avoid an email loop.

This module integrates helpdesk_mgmt with mail_autogenerated_header:
the latter detects such headers on incoming messages and sets a context key
that this module reads in _track_template_skip_autoreply to suppress the
outgoing welcome email.

If follows a similar approach as #1051.

@victoralmau I moved the code from #1054 to here as requested.

The code seems consistent (although I'm not familiar with mail_autogenerated_header)
