We add a new set of builtins called `import_builtins`, which will contain import-related builtins, such as `builtins.path` and `builtins.filterSource`. Both can import paths into the store, with various knobs to alter the result, e.g. filtering, renaming, expected hashes. We introduce `filtered_ingest` which will drive the filtered ingestion via the Nix function via the generator machinery, and then we register the root node to the path info service inside the store. `builtins.filterSource` is very simple, `builtins.path` is a more complicated model requiring the same logic albeit more sophisticated with name customization, file ingestion method and expected SHA-256.
