KVM: selftests: Add global snapshot of kvm_is_forced_emulation_enabled()
Add a global snapshot of kvm_is_forced_emulation_enabled() and sync it to
all VMs by default so that core library code can force emulation, e.g. to
allow for easier testing of the intersections between emulation and other
features in KVM.
