[SPARK-51796] [SQL] Disallow Sort order expressions under non-Sort operators

[mihailoale-db]

What changes were proposed in this pull request?

I propose that we disallow SortOrder expressions under non-Sort operators.

Why are the changes needed?

Following Dataframe program throw an internal error:

val df = sql("SELECT 1 AS name")
df.select(desc("name"))

In this PR we fix is so we throw a more user friendly one.

Does this PR introduce any user-facing change?

Different (more user friendly) error is thrown.

How was this patch tested?

Added test.

Was this patch authored or co-authored using generative AI tooling?

No.

@cloud-fan should we do it like this or should we move checkExpressionUnderUnsupportedOperator check to the begging of the operator match? Thanks

there are cases that an expression containing SortOrder (e.g. ListAgg) can appear in non-sort operators. We need to find out all these cases.
