tools/intel_dp_compliance: Use ARGB8888 format fbs for Gen 10
According to Display WA #1172, to truly bypass the color data on Gen 10
use ARGB8888 instead of XRGB8888 to pass compliance.
v2: Use ARGB8888 format only for video pattern fb, set per pixel alpha
value to 0xff in fill_framebuffer.(Imre)
v3: Set the aplha value for each pixel(Imre)
