Alex Chi Z aaf60819fa feat(pageserver): persist aux file policy in index part (#7668) ...

Part of https://github.com/neondatabase/neon/issues/7462

## Summary of changes

Tenant config is not persisted unless it's attached on the storage
controller. In this pull request, we persist the aux file policy flag in
the `index_part.json`.

Admins can set `switch_aux_file_policy` in the storage controller or
using the page server API. Upon the first aux file gets written, the
write path will compare the aux file policy target with the current
policy. If it is switch-able, we will do the switch. Otherwise, the
original policy will be used. The test cases show what the admins can do
/ cannot do.

The `last_aux_file_policy` is stored in `IndexPart`. Updates to the
persisted policy are done via
`schedule_index_upload_for_aux_file_policy_update`. On the write path,
the writer will update the field.
