fix(messages): unwanted newlines with ext_messages #37733

Problem:  Newlines intended to write messages below the cmdline or to
          mark the start of a new message on message grid are emitted
          through ext_messages. This results in unnecessary newlines for
          a UI that has decoupled its message area from the cmdline.
          msg_col is set directly in some places which is not transmitted
          to msg_show events.
          Various missing message kind for list commands.
          Trailing newlines on various list commands.

Solution: Only emit such newlines without ext_messages enabled.
          Use msg_advance() instead of setting msg_col directly.
          Assign them the "list_cmd" kind.
          Ensure no trailing newline is printed.
