In the next commits we plan to add support to load ICC profiles that are
embedded in images. So we need something more flexible than
load_image().
This patch introduces a new function that, for now, does the same as
load_image(). For now we keep load_image() as well, but the plan is
to drop it later.

Before, cairo-util.h would combine pixman and cairo includes. X11 and
Wayland compositors uses this to load an image as a pixman_image_t but are
forced to include cairo headers. Clients use load_cairo_surface to
load images as cairo_surface_t's, but are forced to include pixman.h.
We move the load_image pixman prototype to its own header, so compositors
can get at the pixman prototype without including cairo.h and clients
can include the cairo based function without including pixman.h.
