This is the final commit that adds
PG17 compatibility with Citus's current capabilities.

You can use Citus community, release-13.0 branch, with PG17.1.

---------

Specifically, this commit:

- Enables PG17 in the configure script.

- Adds PG17 tests to CI using test images that have 17.1

- Fixes an upgrade test: see below for details
In `citus_prepare_upgrade()`, don't drop any_value when upgrading from
PG16+, because PG16+ has its own any_value function. Attempting to do so
results in the error seen in [pg16-pg17
upgrade](https://github.com/citusdata/citus/actions/runs/11768444117/job/32778340003?pr=7661):
```
ERROR:  cannot drop function any_value(anyelement) because it is required by the database system
CONTEXT:  SQL statement "DROP AGGREGATE IF EXISTS pg_catalog.any_value(anyelement)"
```
When 16 becomes the minimum supported Postgres version, the drop
statements can be removed.

---------

Several PG17 Compatibility commits have been merged before this final one.
All these subtasks are done #7653
