Fill out default vram in DeviceDefPostParse

Move filling out the default video (v)ram to DeviceDefPostParse.

This means it can be removed from virDomainVideoDefParseXML
and qemuParseCommandLine. Also, we no longer need to special case
VIR_DOMAIN_VIRT_XEN, since the per-driver callback gets called
before the generic one.
