When splitting out the CoglPath api we saw that we would be left with
inconsistent drawing apis if the drawing apis in core Cogl were lumped
into the cogl_framebuffer_ api considering other Cogl sub-libraries or
that others will want to create higher level drawing apis outside of
Cogl but can't use the same namespace.
So that we can aim for a more consistent style this adds a
cogl_primitive_draw() api, comparable to cogl_path_fill() or
cogl_pango_show_layout() that's intended to replace
cogl_framebuffer_draw_primitive()
Note: the attribute and rectangle drawing apis are still in the
cogl_framebuffer_ namespace and this might potentially change but in
these cases there is no single object representing the thing being drawn
so it seems a more reasonable they they live in the framebuffer
namespace for now.
Note: the cogl_framebuffer_draw_primitive() api isn't removed by this
patch so it can more conveniently be cherry picked to the 1.16 branch so
we can mark it deprecated for a short while. Even though it's marked as
experimental api we know that there are people using the api so we'd
like to give them a chance to switch to the new api.

This adds a test to make sure that if the same pipeline is used to draw
two primitives, one which doesn't need blending because it has an opaque
color associated, and another using a color attribute that requires
blending then Cogl should recognize that it needs to enable blending for
the second primitive even though the pipeline hasn't changed.
