printk: nbcon: Allow drivers to mark unsafe regions and check state
For the write_atomic callback, the console driver may have unsafe
regions that need to be appropriately marked. Provide functions
that accept the nbcon_write_context struct to allow for the driver
to enter and exit unsafe regions.
Also provide a function for drivers to check if they are still the
owner of the console.
