lamptest: Add virtual LEDs to group definition

- During LampTest, if a physical LED state has to be changed, the
  requirement is that we apply the states after the lamp test is
  done. However, there is another requirement that expects the
  accurate state of LEDs to be reported. virtual physical LEDs
  solves this problem.

- If the lamp test is not running, state of virtual_led will be equal
  to real physical LED. However, during LampTest, virtual LED would
  indicate the effective state of the LED as if there was no lamp
  test. Once the lamp test finishes, state of virtual and physical
  would be same.
