Doc: improve protocol spec for logical replication Type messages. protocol.sgml documented the layout for Type messages, but completely dropped the ball otherwise, failing to explain what they are, when they are sent, or what they're good for. While at it, do a little copy-editing on the description of Relation messages.
In passing, adjust the comment for apply_handle_type() to make it clearer that we choose not to do anything when receiving a Type message, not that we think it has no use whatsoever. Per question from Stefen Hillman.
