ui/virtio-gpu: add and use qemu_create_displaysurface_pixman
Add a the new qemu_create_displaysurface_pixman function, to create
a DisplaySurface backed by an existing pixman image. In that case
there is no need to create a new pixman image pointing to the same
backing storage. We can just use the existing image directly.
This does not only simplify things a bit, but most importantly it
gets the reference counting right, so the backing storage for the
pixman image wouldn't be released underneath us.
Use new function in virtio-gpu, where using it actually fixes
use-after-free crashes.
