[PATCH i-g-t] kms_atomic_transition: Split out modeset tests on internal panels

[Imre Deak <imre.deak@intel.com>]

Doing modeset on internal panels may have a considerable overhead due to
the panel specific power sequencing delays. To avoid long test runtimes
in the CI fast-feedback test split out the testing of internal panels
from the plane modeset subtests. Create fast and slow versions of these
new subtests. In the fast one only combinations with all enabled, all
planes disabled or a single plane enable are tested. In the slow one all
plane combinations are tested.
