Subject: OvmfPkg/VirtHstiDxe: do not load driver in confidential guests

The VirtHstiDxe does not work in confidential guests.  There also isn't
anything we can reasonably test, neither flash storage nor SMM mode will
be used in that case.  So just skip driver load when running in a
confidential guest.
