Introduce optional macros for defining APICv, Confidental VM (a.k.a. so called memory encryption), and Hyper-V kvm_x86_ops. Specialized macros will allow vendor code to easily apply a single pattern when wiring up implementations, e.g. SVM using "sev" for Confidential VMs and AVIC for APICv, and VMX currently doesn't support any Condifential VM hooks. Bundling also adds a small amount of self-documentation to the various hooks in kvm-x86-ops.h.
