printk: add dummy printk_force_console_enter/exit helpers 



The newly added interface is broken when PRINTK is disabled:

drivers/tty/sysrq.c: In function '__handle_sysrq':
drivers/tty/sysrq.c:601:9: error: implicit declaration of function 'printk_force_console_enter' [-Wimplicit-function-declaration]
  601 |         printk_force_console_enter();
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/tty/sysrq.c:611:25: error: implicit declaration of function 'printk_force_console_exit' [-Wimplicit-function-declaration]
  611 |                         printk_force_console_exit();
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~

Add empty stub functions for both.
