KVM: allow host header to be included even for !CONFIG_KVM
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.
