* refactor: `IOxReadFilterNode` can always accumulate statistics
`IOxReadFilterNode` used to not emit statistics if one chunk has
duplicates or delete predicates. This is wrong (or at least overly
conservative), because the node itself (or the chunks themselves) do NOT
perform dedup or delete predicate filtering. Instead this is done is
done by parent nodes (`DeduplicateExec` and `FilterExec`) and its their
job to propagate statistics correctly.
Helps w/ #5897.

* refactor: do not run de-dup in ingester for querier requests
This removes the entire de-dup logic from the inegster for querier
requests. Furthermore, it even removes the entire datafusion execution
from the querier and just dumps the in-memory record batches as quickly
as possible. No filters are applied. Note that even prior to this PR,
we've never applied projections (tracked by #5624).
**Pros:**
- speed up query planning within the querier (since we need the ingester
response for state reconciling)
- lowered ingester CPU load
**Cons:**
- more querier<>ingester network traffic
Closes#5602.
* test: extend query test case
* fix: ingester tests
