graphics_utils: Export get_pixel
get_pixel converts a 32bit trgb color into framebuffer format. This
is useful for other code aswell, so export it.
Other functions in the graphics utils code use the name get/set_pixel
aswell, but instead of converting data they get a pixel from the framebuffer
or set a pixel on the framebuffer. To separate from these rename the
function to gu_hex_to_pixel.
