Fu Chen 5bc06fd7d9 [SPARK-36130][SQL] UnwrapCastInBinaryComparison should skip In expression when in.list contains an expression that is not literal
### What changes were proposed in this pull request?

Fix [comment](https://github.com/apache/spark/pull/32488#issuecomment-879315179)
This PR fix rule `UnwrapCastInBinaryComparison` bug. Rule UnwrapCastInBinaryComparison should skip In expression when in.list contains an expression that is not literal.

- In

Before this pr, the following example will throw an exception.
```scala
  withTable("tbl") {
    sql("CREATE TABLE tbl (d decimal(33, 27)) USING PARQUET")
    sql("SELECT d FROM tbl WHERE d NOT IN (d + 1)")
  }
```
- InSet

As the analyzer guarantee that all the elements in the `inSet.hset` are literal, so this is not an issue for `InSet`.

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

No, only bug fix.

### How was this patch tested?

New test.

Closes #33335 from cfmcgrady/SPARK-36130.

Spark SQL

This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.

Spark SQL is broken up into four subprojects:

  • Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
  • Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
  • Hive Support (sql/hive) - Includes extensions that allow users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allow users to run queries that include Hive UDFs, UDAFs, and UDTFs.
  • HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.

Running ./sql/create-docs.sh generates SQL documentation for built-in functions under sql/site, and SQL configuration documentation that gets included as part of configuration.md in the main docs directory.
