Although at this point only QemuGraphicConsole have hw_ops that
implements ui_info() callback, it makes sense to keep the code in the
base QemuConsole, to simplify conditions for the caller.
As of now, the code didn't reach a NULL timer because dpy_set_ui_info()
checks if dpy_ui_info_supported() (hw_ops->ui_info != NULL), which is
false for text_console_ops. This is a bit fragile, let simply allocate
and free the timer in the base class.

Fixing a regression (black screen) caused by a commit 92b58156e7
("ui/gtk: set scanout-mode right before scheduling draw").
The commit 92b58156e7 was made with an assumption that the scanout
mode needs to be set only if the guest scanout is a dmabuf but there
are cases (e.g. virtio-gpu-virgl) where the scanout is still processed
in a form of a texture but is not backed by dmabuf. So it is needed
to put back the line that sets scanout mode in gd_egl_scanout_texture
and gd_gl_area_scanout_texture.
