tty/hvc_console: Add DTR/RTS callback to handle HUPCL control
Introduce a new callback to explicitly handle the HUPCL termios control flag. This prepares for a follow-up commit for the hvc_iucv device driver to improve handling when to drop an established network connection. The callback naming is based on the recently added tty_port interface to facilitate a potential refactoring of the hvc_console to use tty_port functions.
