Gengliang Wang ac1c6aa45c [SPARK-35987][SQL] The ANSI flags of Sum and Avg should be kept after being copied 
### What changes were proposed in this pull request?

Make the ANSI flag part of expressions `Sum` and `Average`'s parameter list, instead of fetching it from the sessional SQLConf.

### Why are the changes needed?

For Views, it is important to show consistent results even the ANSI configuration is different in the running session. This is why many expressions like 'Add'/'Divide' making the ANSI flag part of its case class parameter list.

We should make it consistent for the expressions `Sum` and `Average`

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

Yes, the `Sum` and `Average` inside a View always behaves the same, independent of the ANSI model SQL configuration in the current session.

### How was this patch tested?

Existing UT

Closes #33186 from gengliangwang/sumAndAvg.

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.
