kms_rotation_crc: Adding test for 90/270 rotation

Adding 90/270 rotation testcase for primary and sprite planes.

v2: Added position test for sprite. Checking for gen > 9 for 90/270.
Some cleanup and rebase.
v3: Added test for unsupported tiling and unsupported pixel format for 90/270
v4: Added the legacy commit to initiate modeset in the negative test(Tvrtko)
