bake: Optimize cache handling for the baking process. - Get rid of the 2-level pipeline runs... handle a single set of passes. - Go back to load/render segments/layout passes for pages. - Add descriptions of what each job batch does. - Improve the taxonomy pipeline so it doesn't re-bake terms that don't need to be re-baked. - Simplify some of the code.
