lib/igt_draw: add support for RGB565 and XRGB2101010

Browse Source 
We need to test those pixel formats on the FBC code, so let's make
sure the drawing library works on them first.

v2: Update the gtkdoc (Daniel).

* All functions assume the buffers are in the XRGB 8:8:8 format.
*
* This library only claims support for some pixel formats, but adding support
* for more formats should be faily easy now that we support both 16bpp and
* 32bpp. If you need a new pixel format, make sure you update both this file
