domain_conf.c: move primary video check to validate callback

This check isn't exclusive to XML parsing. Let's move it to
virDomainDefVideoValidate() in domain_validate.c

We don't have a failure test for this scenario, so a new test called
'video-multiple-primaries' was added to test this failure case.
