I thought of a better name at last, that shows its relation
to virDomainGetLaunchSecurityInfo without implying that they
are the direct inverse of each other:

  virDomainSetLaunchSecurityState(...)

Also, we whould bear in mind that the set of state parameters
may be differnt for vendors other than AMD, and even later
generations of AMD SEV might want more parameters.

So lets use a 'virTypedParameter' array for this methodeg

  virDomainSetLaunchSecurityState(virDomainPtr dom,
                                  virTypedParameterPtr params,
                                  int nparams,
                                  unsigned int flags);

Daniel
