pgsql: add subprotocol-states

Description

In order to keep adding PostgreSQL support in Suricata, cover sub-protocol states:
- Extended query
- COPY operators
- Replication
- Function call
- Termination

Even though PostgreSQL refers to those as sub-protocols, to Suri, they're more like sub-states, where we'll expect to parse different sets of messages.

These could then be used in some Detect situations as well.

More details about each sub-protocol can be found in the protocol official documentation: https://www.postgresql.org/docs/13/protocol-flow.html

Reading and re-reading https://www.postgresql.org/docs/13/protocol-flow.html#PROTOCOL-COPY, I wonder if this shouldn't be veered towards having different modes, that could then accept and process certain kinds of messages -- and if there is any difference in this, or just terminology. Maybe there is, because, for instance, both Simple Query and Extended Query are covered by the command-processing mode.

On the other hand, this may be a level of detail that is only important to the pgsql server to know, and not to Suri... (leaving these thoughts here to keep them saved)
