This adds experimental 2.0 api replacements for the cogl_rectangle[_*]
functions that don't depend on having a current pipeline set on the
context via cogl_{set,push}_source() or having a current framebuffer set
on the context via cogl_push_framebuffer(). The aim for 2.0 is to switch
away from having a statefull context that affects drawing to having
framebuffer drawing apis that are explicitly passed a framebuffer and
pipeline.
To test this change several of the conformance tests were updated to use
this api instead of cogl_rectangle and
cogl_rectangle_with_texture_coords. Since it's quite laborious going
through all of the conformance tests the opportunity was taken to make
other clean ups in the conformance tests to replace other uses of
1.x api with experimental 2.0 api so long as that didn't affect what was
being tested.
