[Intel-gfx] [PATCH i-g-t 6/8] kms_frontbuffer_tracking: Add option to allow running tescases with FBC disabled.

[Rodrigo Vivi]

We need to be able to identify if the issue is feature related
or caused by another bug.

Also this feature allow users to have a visual feedback of what to
expect when running the test case for real.
