core: Continue PieCrust3 refactor, simplify pages.
The asset pipeline is still the only function pipeline at this point.
* No more `QualifiedPage`, and several other pieces of code deleted.
* Data providers are simpler and more focused. For instance, the page iterator
doesn't try to support other types of items.
* Route parameters are proper known source metadata to remove the confusion
between the two.
* Make the baker and pipeline more correctly manage records and record
histories.
* Add support for record collapsing and deleting stale outputs in the asset
pipeline.
