[cogl-material] Converts clutter-texture/clutter-clone-texture to the material API

Browse Source 
This converts clutter-texture to use the new CoglMaterial API instead of
cogl_texture_rectangle.

This change does not add multi-texturing support to Clutter, it's more about
aiming to deprecate cogl_texture_rectangle, and moving everything over to the
cogl_set_source(material); cogl_draw_somthing(); coding pattern.

With this patch, the code can be built with/without CoglMaterial support so we
can do comparisons of the old/new code for a transient period. (look for the
USE_COGL_MATERIAL define)

Note: The FBO paths haven't currently been tested, so they may need some
tweaks.
