fix(terminal): scrollback delete lines immediately #18832

* on_scrollback_option_changed renamed to adjust_scrollback. The
  function name did not correspond to what it was doing. It is
  called unconditionally in every refresh of the terminal
  unrelated if the scrollback option was changed.
* new on_scrollback_option_changed function, which calls
  refresh_terminal, which then calls adjust_scrollback
* terminal_check_size is not the appropriate function to call when the
  option is changed since it only conditionally adjusts the scrollback.
  Use the new on_scrollback_option_changed
