gengjiaan 9273d4250d [SPARK-33045][SQL][FOLLOWUP] Support built-in function like_any and fix StackOverflowError issue 
### What changes were proposed in this pull request?
Spark already support `LIKE ANY` syntax, but it will throw `StackOverflowError` if there are many elements(more than 14378 elements). We should implement built-in function for LIKE ANY to fix this issue.

Why the stack overflow can happen in the current approach ?
The current approach uses reduceLeft to connect each `Like(e, p)`, this will lead the the call depth of the thread is too large, causing `StackOverflowError` problems.

Why the fix in this PR can avoid the error?
This PR support built-in function for `LIKE ANY` and avoid this issue.

### Why are the changes needed?
1.Fix the `StackOverflowError` issue.
2.Support built-in function `like_any`.

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

### How was this patch tested?
Jenkins test.

Closes #30465 from beliefer/SPARK-33045-like_any-bak.

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.
