Currently, vkms only supports the rotate-180, reflect-x and reflect-y
properties. 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.
