This commit removes the `invalidate_for_index` logic that was responsible for invalidating all expr cache entries for objects that could potentially make use of a newly added index. There are two reasons to think we don't want this logic: * Currently, bootstrapping plans dataflows in ID order. A new index will always have a greater ID than existing objects, so will never be available during the planning of those objects, regardless of whether or not the cache entries for them are invalidated. * Even if the replanning worked as intended, we don't actually want it. Changing the plan means breaking compute reconciliation, which means causing unavailability until the affected dataflows have rehydrated. We do want replanning across version upgrades, but in that case the entire expr cache is cleared anyway, so no special handling is needed.

All calls to update are now passing an empty set to the invalidate_ids parameter, so you could consider removing that parameter, and downstream things. (But it's also ok to leave that to follow-up PRs.)

I left it in because I want to follow up with a PR that also updates the cache in response to DDL. And I suspect there is a good chance we'll need to pass this argument when removing plans on DROP.

Because of the first point, this is not expected to change anything about the current behavior. Because of the second point, this is a necessary (though not sufficient) precondition for merging #34859.
