fix: Disable automations on auto-reply emails (#12101)

The term "sorcerer’s apprentice mode" is defined as a bug in a protocol
where, under some circumstances, the receipt of a message causes
multiple messages to be sent, each of which, when received, triggers the
same bug. - RFC3834

Reference: https://github.com/chatwoot/chatwoot/pull/9606

This PR:
- Adds an auto_reply attribute to message.
- Adds an auto_reply attribute to conversation. 
- Disable conversation_created / conversation_opened event if auto_reply
is set.
- Disable message_created event if auto_reply is set.
