When doing a full atomic modeset, kernel should fail if the flag
DRM_MODE_ATOMIC_ALLOW_MODESET is not set. Let's add this test as part of
Intel-GPU-Tools. The test procedure is the following:

- Try to do atomic commit without DRM_MODE_ATOMIC_ALLOW_MODESET flag.
  Kernel should reject this request.
- Do full modeset
- Enable DRM_MODE_ATOMIC_ALLOW_MODESET and try to do atmic commit.
  Kernel should now allow atomic modeset.

For: VIZ-6955

This tests one source of allow_modeset. There are 2 more:
Changing only the active property, which is similar to toggling dpms.
Assigning a different connector to the current crtc

I think the active property should be tested too at least.

Connector testing seems to need this. I'll move this inside igt_fixture
as that is the better place for these.

Ok. I'll add active property testing as one of the subtests.
