[Intel-gfx] [PATCH igt 3/6] kms_frontbuffer_tracking: set the universal planes cap in the setup

... instead of just setting it for the fullscreen_plane subtest and
then unsetting it. We want to use it more, so just make sure all the
code knows how to deal with multiple planes per CRTC.
This also allows us to do some upfront caching of the plane
information, so the code for the tests gets simpler.
There's a new test that's going to use all these changes.
