This CL adds a VTS test for the DICE HAL, and a test specific for
demotion testing. Demotion testing leaves the device in a permanently
modified state untill the next reboot, which is why it needs a special
test config. The current test config restarts the device before testing,
in a followup the device also has to reboot after the test.
