drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_rgb565()

Browse source

Extend the existing test cases to test the conversion from XRGB8888 to
RGB565.

The documentation and the color picker available on [1] are useful
resources to understand this patch and validate the values returned by
the conversion function.
