sna/gen3: Convert the clear-color from picture->format to a8r8g8b8
The shaders treat colours as an argb value, however the clear color is
stored in the pixmap's native format (a8, r5g6b5, x8r8g8b8 etc). So
before using the value of the clear color as a solid we need to convert
it into the a8r8g8b8 format.
