* test: tests in the reorg planner and query tests for merging parquet files
* fix: use 20 files

* test: use `EXPLAIN ANALYZE` for SQL metric tests
Needs a bit more infra (due to normalization), but this seems to be
worth it so we can easily hook up more metrics in the future.
* docs: explain regexes
It should be always clear from the context to which table a chunk
belongs.
I think having a table name bound to a chunk goes back to a time where
chunks had multiple tables.
Helps with #6049.

* refactor: simplify `QueryChunk` data access
We have only two types for chunks (now that the RUB is gone):
1. In-memory RecordBatches
2. Parquet files
Loads of logic is duplicated in the different `read_filter`
implementations. Also `read_filter` hides a solid amount of logic from
DataFusion, which will prevent certain (future) optimizations. To enable #5897
and to simplify the interface, let the chunks return the data (batches
or metadata for parquet files) directly and let `iox_query` perform the
actual heavy-lifting.

With #5963 merged, all chunks now provide a summary (even though it may
not contain data for all columns). So let's make it mandatory, which
also removes a few 🙈-style `.except(...)` calls.

Use the table summary instead. This allows us to have a single mechanism
that both IOx and DataFusion understand. This basically lifts the "basic
table summary" mechanism that the querier uses to `iox_query` and let
the compactor and ingester use the same mechanism.
While not strictly necessary, simplifying the `QueryChunk[Meta]`
interface helps with #5897.

This commit makes use of the partition buffer state machine introduced
in https://github.com/influxdata/influxdb_iox/pull/5943.
This commit significantly changes the buffering, and querying, of data
from a partition, swapping out the existing "DataBuffer" for the new
state machine implementation (itself simplified due to temporary lack of
incremental snapshot generation, see #5944).
This commit simplifies the query path, removing multiple types that
wrapped one-another to pass around various state necessary to perform a
query, with various query functions needing different types or
combinations of types. The query path now operates using a single type
(named "QueryAdaptor") that provides a queryable interface over the set
of RecordBatch returned from a partition.
There is significantly increased testing of the PartitionData itself,
covering data in various states and the ordering of returned RecordBatch
(to ensure correct materialisation of updates). There are also
invariants upheld by the type system / compiler to minimise the
complexities of working with empty batches & states, and many asserts
that ensure (mostly existing!) invariants are upheld.
We basically assume everywhere that a column falls into one of the three
known categories (time, tag, field), so lets encode this in our type
system instead of defining "unknown" as "undefined behavior, may or may
not crash".

* feat: have a logical plan that is aware of no-deduplication
* feat: build physical scan plan that does not do deduplication
* chore: cleaup
* test: logical plans for scan with and without deduplication
* chore: clean up and a small refactor
* refactor: remove asserts on plan and rename make enable_deduplication default
* refactor: rename disable_deduplication to enable_deduplication
Databases are NOT required to project chunks (in practice this is only
done by the querier for ingester-based chunks). Instead `iox_query`
should (and already does) add the right stream adapters to project
chunks or to create NULL-columns. Removing the special handling from the
test setup makes it easier to understand and also less likely that
`iox_query` starts to rely on this behavior.
Helps with #5897.

- remove generic that is basically unused (`group_potential_duplicates`
is always called w/ `Arc<dyn QueryChunk>`)
- remove half-baked `impl` that is unused
Helps w/ #5897.

* 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.

Now that we read throw `ParquetExec`, `ROW_GROUP_READ_SIZE` is no longer
used.

Use the proper top-level DataFusion context and register the object
store there.
Note that we still hide the `ParquetExec` behind an opaque record batch
stream. Fixing that is next on my list.
Helps with #5897.

* refactor: replace `croaring` with `roaring`
With the read buffer gone, roaring bitmaps are only used to calculate
series sets and these calculations are pretty much possible with the
pure-Rust version. Also I don't deem that that performance-critical
(compared to the roaring bitmaps in the read buffer core).
This removes a bunch of dependencies, mostly because `bindgen` is gone.
This also removes our "croaring architecture detection" hack.
* refactor: replace manual roaring sets with arrow
