i-g-t: Adding plane scaling test case

This patch is adding i-g-t plane scaling test case to test couple basic
display plane scaling usages. Additional test scenarios can be added later.

v2:
-Added iterative scaling to visually observe scaling (me)

v3:
-Added a flag to control primary plane scaling (me)

v4:
-Use new tiled types when calling igt_create_fb (me)
