[stdlib]: Add a generic critical path graph module

This brings us closer to productionizing and generalizing
the critical path algorithm. Still in experimental until the API
is fully fledged.

2 functions extracted out:
1. _critical_path(graph_table, root_table)
2. _critical_path_intervals(graph_table, root_table, interval_table)

The first works completely in id space, the second 'flattens' for the UI
