The wrapper required the implementation of the `ArrayParam`, because `Array[T]` is hard to obtain from Python. `ArrayParam` has an extra function called `wCast` which is an internal function to obtain `Array[T]` from `Seq[T]`

### What changes were proposed in this pull request?
`org.apache.spark.sql.kafka010.KafkaDelegationTokenSuite` failed lately. After had a look at the logs it just shows the following fact without any details:
```
Caused by: sbt.ForkMain$ForkError: sun.security.krb5.KrbException: Server not found in Kerberos database (7) - Server not found in Kerberos database
```
Since the issue is intermittent and not able to reproduce it we should add more debug information and wait for reproduction with the extended logs.

### Why are the changes needed?
Failing test doesn't give enough debug information.

### Does this PR introduce any user-facing change?
No.

### How was this patch tested?
I've started the test manually and checked that such additional debug messages show up:

…ly equivalent children in `RewriteDistinctAggregates`

### What changes were proposed in this pull request?

In `RewriteDistinctAggregates`, when grouping aggregate expressions by function children, treat children that are semantically equivalent as the same.

### Why are the changes needed?

This PR will reduce the number of projections in the Expand operator when there are multiple distinct aggregations with superficially different children. In some cases, it will eliminate the need for an Expand operator.

Example: In the following query, the Expand operator creates 3\*n rows (where n is the number of incoming rows) because it has a projection for each of function children `b + 1`, `1 + b` and `c`.

```
create or replace temp view v1 as
select * from values
(1, 2, 3.0),
(1, 3, 4.0),
(2, 4, 2.5),
(2, 3, 1.0)
v1(a, b, c);

select
  a,
  count(distinct b + 1),
  avg(distinct 1 + b) filter (where c > 0),
  sum(c)
from
  v1
group by a;
```
The Expand operator has three projections (each producing a row for each incoming row):
```
[a#87, null, null, 0, null, UnscaledValue(c#89)], <== projection #1 (for regular aggregation)
[a#87, (b#88 + 1), null, 1, null, null],          <== projection #2 (for distinct aggregation of b + 1)
[a#87, null, (1 + b#88), 2, (c#89 > 0.0), null]], <== projection #3 (for distinct aggregation of 1 + b)
```
In reality, the Expand only needs one projection for `1 + b` and `b + 1`, because they are semantically equivalent.

With the proposed change, the Expand operator's projections look like this:
```
[a#67, null, 0, null, UnscaledValue(c#69)],  <== projection #1 (for regular aggregations)
[a#67, (b#68 + 1), 1, (c#69 > 0.0), null]],  <== projection #2 (for distinct aggregation on b + 1 and 1 + b)
```
With one less projection, Expand produces 2\*n rows instead of 3\*n rows, but still produces the correct result.

In the case where all distinct aggregates have semantically equivalent children, the Expand operator is not needed at all.

Benchmark code in the JIRA (SPARK-40382).

…edExpression()

### What changes were proposed in this pull request?

In `EquivalentExpressions.addExpr()`, add a guard `supportedExpression()` to make it consistent with `addExprTree()` and `getExprState()`.

### Why are the changes needed?

This fixes a regression caused by apache#39010 which added the `supportedExpression()` to `addExprTree()` and `getExprState()` but not `addExpr()`.

One example of a use case affected by the inconsistency is the `PhysicalAggregation` pattern in physical planning. There, it calls `addExpr()` to deduplicate the aggregate expressions, and then calls `getExprState()` to deduplicate the result expressions. Guarding inconsistently will cause the aggregate and result expressions go out of sync, eventually resulting in query execution error (or whole-stage codegen error).

### Does this PR introduce _any_ user-facing change?

This fixes a regression affecting Spark 3.3.2+, where it may manifest as an error running aggregate operators with higher-order functions.

Example running the SQL command:
```sql
select max(transform(array(id), x -> x)), max(transform(array(id), x -> x)) from range(2)
```
example error message before the fix:
```
java.lang.IllegalStateException: Couldn't find max(transform(array(id#0L), lambdafunction(lambda x#2L, lambda x#2L, false)))#4 in [max(transform(array(id#0L), lambdafunction(lambda x#1L, lambda x#1L, false)))#3]
```
after the fix this error is gone.

### How was this patch tested?

Added new test cases to `SubexpressionEliminationSuite` for the immediate issue, and to `DataFrameAggregateSuite` for an example of user-visible symptom.

Closes apache#40473 from rednaxelafx/spark-42851.

### What changes were proposed in this pull request?

In `EquivalentExpressions.addExpr()`, add a guard `supportedExpression()` to make it consistent with `addExprTree()` and `getExprState()`.

### Why are the changes needed?

This fixes a regression caused by apache#39010 which added the `supportedExpression()` to `addExprTree()` and `getExprState()` but not `addExpr()`.
