buffer: Add a store_created bit field member

This adds a store_created bit field to CoglBuffer so we know if the
underlying buffer has been allocated yet. Previously the code was trying
to do something really wrong by accidentally using the
COGL_PIXEL_ARRAY_FLAG_IS_SET macro (note "PIXEL_ARRAY") and what is more
odd was the declaration of a CoglPixelArray *pixel_array in
cogl-buffer.c which the buffer was being cast too before calling using
the macro. Probably this was the fall-out of some previous code
re-factoring.
