primitive: Adds convenience constructors
This adds convenience primitive constructors named like: cogl_primitive_new_p3 or cogl_primitive_new_p3c4 or cogl_primitive_new_p3t2c4 where the letters correspond to the interleved vertex attributes layouts such as CoglP3Vertex which is a struct with 3 float x,y,z members for the [p]osition, or CoglP3T2C4Vertex which is a struct with 3 float x,y,z members for the [p]osition, 2 float s,t members for the [t]exture coordinates and 4 unsigned byte r,g,b,a members for the [c]olor. The hope is that people will find these convenient enough to replace cogl_polygon.
