Test the conversion from XRGB8888 to RGB332.

What is tested?

• Different values for the X in XRGB8888 to make sure it is ignored
• Different clip values: Single pixel and full and partial buffer
• Well known colors: White, black, red, green, blue, magenta, yellow and cyan
• Other colors: Randomly picked
• Destination pitch

How to run the tests?

$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm \ --kconfig_add CONFIG_VIRTIO_UML=y \ --kconfig_add CONFIG_UML_PCI_OVER_VIRTIO=y

It's not clear to me why you would need VIRTIO here? The Kunit config file should be enough to run the tests properly
