John Spray e78d1e2ec6 tests: tighten readability rules in test_location_conf_churn (#12059) ...

## Problem

Checking the most recent state of pageservers was insufficient to
evaluate whether another pageserver may read in a particular generation,
since the latest state might mask some earlier AttachedSingle state.

Related: https://github.com/neondatabase/neon/issues/11348

## Summary of changes

- Maintain a history of all attachments
- Write out explicit rules for when a pageserver may read
