[Intel-gfx] [PATCH] igt/kms_rotation_crc: Add a subtest to validate Y-tiled obj + Y fb modifier (v2)

[Vivek Kasireddy]

The main goal of this subtest is to verify whether flipping a
framebuffer with a Y fb modifier (90/270 degree rotation) and
with an associated Y-tiled object works or not.

v2: Do not call paint_squares and just use one output.
