roll: pigweed pw_containers: Refactor docs

pw_containers has grown larger, and the doc treatment of different
containers has been inconsistent. As a precursor to adding more size
reports, this CL reorganizes the module docs into groups of container
types: lists, maps, queues, sets, vectors and utilities.

This makes it easier to navigate the docs, find the container you may be
looking for, and see the relevant information for that container, such
as examples, API references, and code size reports.
