Therefore, improve the vkms IGT test coverage by adding the rotate-90 property to vkms. The rotation was implement by software: rotate the way the blending occurs by making the source x axis be the destination y axis and the source y axis be the destination x axis. Tested with igt@kms_rotation_crc@primary-rotation-90, igt@kms_rotation_crc@sprite-rotation-90, and igt@kms_rotation_crc@sprite-rotation-90-pos-100-0.
