Yuming Wang 78f9043862 [SPARK-31912][SQL][TESTS] Normalize all binary comparison expressions
### What changes were proposed in this pull request?

This pr normalize all binary comparison expressions when comparing plans.

### Why are the changes needed?

Improve test framework, otherwise this test will fail:
```scala
  test("SPARK-31912 Normalize all binary comparison expressions") {
    val original = testRelation
      .where('a === 'b && Literal(13) >= 'b).as("x")
    val optimized = testRelation
      .where(IsNotNull('a) && IsNotNull('b) && 'a === 'b && 'b <= 13 && 'a <= 13).as("x")
    comparePlans(Optimize.execute(original.analyze), optimized.analyze)
  }
```

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

### How was this patch tested?

Manual test.

Closes #28734 from wangyum/SPARK-31912.

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.
