video: screen_info: Add pixel-format helper for linear framebuffers
Add screen_info_pixel_format(), which converts a screen_info's information about the color format to struct pixel_format. The encoding within the screen_info structure is complex and therefore prone to errors. Later patches will convert callers to use the pixel format.
