KVM: selftests: Move "struct hv_enlightenments" to x86_64/svm.h

[ Upstream commit 381fc63ac0754e05d3921e9d399b89dfdfd2b2e5 ]

Move Hyper-V's VMCB "struct hv_enlightenments" to the svm.h header so
that the struct can be referenced in "struct vmcb_control_area".
Alternatively, a dedicated header for SVM+Hyper-V could be added, a la
x86_64/evmcs.h, but it doesn't appear that Hyper-V will end up needing
a wholesale replacement for the VMCB.

No functional change intended.
