    x86/svm: Introduce svm-types.h
    
    In order to reduce the header tangle around xen/sched.h, we need to split
    types away from other declarations.
    
    Introduce a new hvm/svm-types.h to do this, including it from hvm/domain.h 
and
    hvm/vcpu.h, and dropping all other inclusions of svm/vmcb.h and
    svm/nestedhvm.h
    
    No functional change.
