bake: Make pipeline processing multi-process.
Not many changes here, as it's pretty straightforward, but an API change for
processors so they know if they're being initialized/disposed from the main
process or from one of the workers. This makes it possible to do global stuff
that has side-effects (e.g. create a directory) vs. doing in-memory stuff.
