cogl: Include the pipeline name and program number in debug logs

Browse source 
When running with COGL_DEBUG=show-source, log what pipeline and shader
program is used when painting, and what shader source code corresponds
to each shader program.

This helps identify what shader is used when painting to what
framebuffer.
