[native] Add support for TPC-H Connector Protocol Bindings

The protocol bindings for TPC-H Connector were manually added in PR prestodb#18367.
These bindings will now be generated automatically.
The following improvements have been made:

1. Improve README of presto_cpp/presto_protocol.
2. Add default make target to generate Presto protocol files.
3. Include TpchConnector classes in the yml file.
4. Extend special Connector files to support tpch.
5. Customize TpchTransactionHandle since the corresponding class in Java is an enum.
6. Customize TpchColumnHandle since we require an implementation of operator<().
