[SPARK-31563][SQL] Fix failure of InSet.sql for collections of Catalyst's internal types
### What changes were proposed in this pull request?
In the PR, I propose to fix the `InSet.sql` method for the cases when input collection contains values of internal Catalyst's types, for instance `UTF8String`. Elements of the input set `hset` are converted to Scala types, and wrapped by `Literal` to properly form SQL view of the input collection.
### Why are the changes needed?
The changes fixed the bug in `InSet.sql` that makes wrong assumption about types of collection elements. See more details in SPARK-31563.
### Does this PR introduce any user-facing change?
Highly likely, not.
### How was this patch tested?
Added a test to `ColumnExpressionSuite`
Closes #28343 from MaxGekk/fix-InSet-sql.
