[SPARK-51292][SQL] Remove unnecessary inheritance from PlanTestBase, …

…ExpressionEvalHelper and PlanTest

### What changes were proposed in this pull request?
This PR proposes to remove unnecessary inheritance from `PlanTestBase`, `ExpressionEvalHelper` and `PlanTest`.

### Why are the changes needed?

1. Some class extends both `ExpressionEvalHelper` and `PlanTestBase`, but `ExpressionEvalHelper` already extends `PlanTestBase`.
```
trait ExpressionEvalHelper extends ScalaCheckDrivenPropertyChecks with PlanTestBase {
  self: SparkFunSuite =>
  ...
}
```
2. Class `NullDownPropagationSuite`, `OptimizeCsvExprsSuite`, `PushFoldableIntoBranchesSuite` doesn't need `ExpressionEvalHelper` at all.
3. Some class extends both `QueryTest` and `PlanTest`, but `QueryTest` already extends `PlanTest`.
```
abstract class QueryTest extends PlanTest {
...
}
```

### Does this PR introduce _any_ user-facing change?
'No'.
Just update the inner code.

### How was this patch tested?
GA.

### Was this patch authored or co-authored using generative AI tooling?
'No'.

Closes #50047 from beliefer/SPARK-51292.
