The new context tracking subsystem unconditionally includes kvm_host.h headers for the guest enter/exit macros. This causes a compile failure when KVM is not enabled. Fix by adding an IS_ENABLED(CONFIG_KVM) check to kvm_host so it can be included/compiled even when KVM is not enabled.

This broke the PPC non-KVM build, which was relying on stub functions in kvm_ppc.h, which relies on "struct vcpu" in kvm_host.h.
Why can't the entirety kvm_host.h be included regardless of CONFIG_KVM, just like most other feature-specific headers? Why can't the if/else just go around the functions that you want to stub out for non-KVM builds?
