Robert Bragg 66cc330c0b Loosen the guard around clutter_backend_get_cogl_context
We were only exposing clutter_backend_get_cogl_context() if
COGL_ENABLE_EXPERIMENTAL_2_0_API had been defined but the CoglContext
api is also available if COGL_ENABLE_EXPERIMENTAL_API has been defined.

As it was it meant that code opting into the experimental Cogl api
but not limiting to the 2.0 only api would have to #define
COGL_ENABLE_EXPERIMENTAL_2_0_API before including clutter.h but make
sure it wasn't defined when including cogl.h which was particularly
awkward.
