KVM: x86: selftests: test simultaneous uses of V_IRQ from L1 and L0

Test that if:

* L1 disables virtual interrupt masking, and INTR intercept.

* L1 setups a virtual interrupt to be injected to L2 and enters L2 with
  interrupts disabled, thus the virtual interrupt is pending.

* Now an external interrupt arrives in L1 and since
  L1 doesn't intercept it, it should be delivered to L2 when
  it enables interrupts.

  to do this L0 (abuses) V_IRQ to setup an
  interrupt window, and returns to L2.

* L2 enables interrupts.
  This should trigger the interrupt window,
  injection of the external interrupt and delivery
  of the virtual interrupt that can now be done.

* Test that now L2 gets those interrupts.

This is the test that demonstrates the issue that was
fixed in the previous patch.
