SEV: QMP support for Inject-Launch-Secret

[Tobin Feldman-Fitzthum]

This is an update to part of a patch submitted previously to
provide support for injecting a secret blob into guest memory
using AMD SEV.

The user provides a header and a wrapped secret blob via QMP,
which are provided to the AMD Secure Processor and injected
into the guest.

Note that this patch requires the user to provide the guest
physical address where the secret will be injected via QMP.
