[PATCH v3 04/14] x86/svm: make emulate.h private

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

The header asm/hvm/svm/emulate.h is used only internally by the SVM code,
so it can be changed into a private header.

Take the opportunity to use an SPDX tag for the licence.

No functional change intended.
