Key-less datamodel 1: scrap InstanceKey from public logging APIs (#…

…5395)

This just removes `InstanceKey`s from the archetypes where they were
exposed, and updates all tests/examples/APIs/etc accordingly.

Nothing else changes. Internally, everything is still driven by
autogenerated instance keys.

The `num_instances` field and the associated log-time check ("0, 1, or
N?") are still there.

Part of a series of PR to migrate to a key-less, PoV-less,
component-based (as opposed to archetype-based) query model:
