ui/console: Add placeholder flag to message surface

Browse source 
The surfaces created with former qemu_create_message_surface
did not display the content from the guest and always contained
simple messages describing the reason.

A display backend may want to hide the window showing such a
surface. This change renames the function to
qemu_create_placeholder_surface, and adds "placeholder" flag; the
display can check the flag to decide to do anything special like
hiding the window.
