Almost all tests do this anyway and the ones that don't don't
appear to care. Only vmx_set_nested_state_test assumes that
a feature (VMX) is disabled until later setting the supported
CPUIDs. It's better to disable that explicitly anyway.

ctrl_exit_rev/ctrl_pin_rev/basic variables are only used in
vmx_preemption_timer_test.c, just move them there.

When a nested VM with a VMX-preemption timer is migrated, verify that the
nested VM and its parent VM observe the VMX-preemption timer exit close to
the original expiration deadline.
