pipeline: only maintain breadcrumb for debug builds

Browse Source 
This ensures we only add a static_breadcrumb pointer to every
CoglPipeline when build with debugging enabled. Since applications may
allocate a lot of pipelines we want to keep the basic size of pipelines
(ignoring optional sparse state) down to a minimum.
