qemu: validate vhost-user video backend in qemu_domain.c

Browse Source 
The goal is to move all of the video device validation to a single place
and use domain caps to validate the supported video device models. Since
qemuDomainDeviceDefValidateVideo() is called from
qemuProcessStartValidate(), these changes should not change anny
behavior.
