qemuDomainManagedSaveDefineXML: Add top-level flag validation

The implementation for managed save uses 'qemuDomainSaveImageDefineXML'
internally which validates the flags. To have a top level flag
validation for the upcoming flag introspection export the supported
flags as a macro and add a 'virCheckFlags' to
'qemuDomainManagedSaveDefineXML'.
