MSQ: Validate that strings and string arrays are not mixed. (#15920) 

* MSQ: Validate that strings and string arrays are not mixed.

When multi-value strings and string arrays coexist in the same column,
it causes problems with "classic MVD" style queries such as:

  select * from wikipedia -- fails at runtime
  select count(*) from wikipedia where flags = 'B' -- fails at planning time
  select flags, count(*) from wikipedia group by 1 -- fails at runtime

To avoid these problems, this patch adds type verification for INSERT
and REPLACE. It is targeted: the only type changes that are blocked are
string-to-array and array-to-string. There is also a way to exclude
certain columns from the type checks, if the user really knows what
they're doing.

* Fixes.

* Tests and docs and error messages.

* More docs.

* Adjustments.

* Adjust message.

* Fix tests.

* Fix test in DV mode.

2. Set [`finalizeAggregations: false`](reference.md#context-parameters) in your context. This causes aggregation
functions to write their internal state to the generated segments, instead of the finalized end result, and enables
further aggregation at query time.
3. See [ARRAY types](../querying/arrays.md#sql-based-ingestion-with-rollup) for information about ingesting `ARRAY` columns
4. See [multi-value dimensions](../querying/multi-value-dimensions.md#sql-based-ingestion-with-rollup) for information to ingest multi-value VARCHAR columns

When you do all of these things, Druid understands that you intend to do an ingestion with rollup, and it writes
rollup-related metadata into the generated segments. Other applications can then use [`segmentMetadata`

### SQL-based ingestion
Arrays can also be inserted with [SQL-based ingestion](../multi-stage-query/index.md) when you include a query context parameter [`"arrayIngestMode":"array"`](../multi-stage-query/reference.md#context-parameters).
#### `arrayIngestMode`
Arrays can be inserted with [SQL-based ingestion](../multi-stage-query/index.md) when you include the query context
parameter `arrayIngestMode: array`.
When `arrayIngestMode` is `array`, SQL ARRAY types are stored using Druid array columns. This is recommended for new
tables.
When `arrayIngestMode` is `mvd`, SQL `VARCHAR ARRAY` are implicitly wrapped in [`ARRAY_TO_MV`](sql-functions.md#array_to_mv).
This causes them to be stored as [multi-value strings](multi-value-dimensions.md), using the same `STRING` column type
as regular scalar strings. SQL `BIGINT ARRAY` and `DOUBLE ARRAY` cannot be loaded under `arrayIngestMode: mvd`. This
is the default behavior when `arrayIngestMode` is not provided in your query context, although the default behavior
may change to `array` in a future release.
When `arrayIngestMode` is `none`, Druid throws an exception when trying to store any type of arrays. This mode is most
useful when set in the system default query context with `druid.query.default.context.arrayIngestMode = none`, in cases
where the cluster administrator wants SQL query authors to explicitly provide one or the other in their query context.
The following table summarizes the differences in SQL ARRAY handling between `arrayIngestMode: array` and
`arrayIngestMode: mvd`.
| SQL type | Stored type when `arrayIngestMode: array` | Stored type when `arrayIngestMode: mvd` (default) |
|---|---|---|
|`VARCHAR ARRAY`|`ARRAY<STRING>`|[multi-value `STRING`](multi-value-dimensions.md)|
|`BIGINT ARRAY`|`ARRAY<LONG>`|not possible (validation error)|
|`DOUBLE ARRAY`|`ARRAY<DOUBLE>`|not possible (validation error)|
In either mode, you can explicitly wrap string arrays in `ARRAY_TO_MV` to cause them to be stored as
[multi-value strings](multi-value-dimensions.md).
When validating a SQL INSERT or REPLACE statement that contains arrays, Druid checks whether the statement would lead
to mixing string arrays and multi-value strings in the same column. If this condition is detected, the statement fails
validation unless the column is named under the `skipTypeVerification` context parameter. This parameter can be either
a comma-separated list of column names, or a JSON array in string form. This validation is done to prevent accidentally
mixing arrays and multi-value strings in the same column.
#### Examples
