Currently, vkms only supports the rotate-90 and rotate-180 properties.
Therefore, improve the vkms IGT test coverage by adding the rotate-270
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 and reverse-read the axis.
Tested with igt@kms_rotation_crc@primary-rotation-270, and
igt@kms_rotation_crc@sprite-rotation-270.
