[SPARK-31489][SQL] Fix pushing down filters with java.time.LocalDate values in ORC 
### What changes were proposed in this pull request?
Convert `java.time.LocalDate` to `java.sql.Date` in pushed down filters to ORC datasource when Java 8 time API enabled.

Closes #28272

### Why are the changes needed?
The changes fix the exception raised while pushing date filters when `spark.sql.datetime.java8API.enabled` is set to `true`:
```
Wrong value class java.time.LocalDate for DATE.EQUALS leaf
java.lang.IllegalArgumentException: Wrong value class java.time.LocalDate for DATE.EQUALS leaf
	at org.apache.hadoop.hive.ql.io.sarg.SearchArgumentImpl$PredicateLeafImpl.checkLiteralType(SearchArgumentImpl.java:192)
	at org.apache.hadoop.hive.ql.io.sarg.SearchArgumentImpl$PredicateLeafImpl.<init>(SearchArgumentImpl.java:75)
	at org.apache.hadoop.hive.ql.io.sarg.SearchArgumentImpl$BuilderImpl.equals(SearchArgumentImpl.java:352)
	at org.apache.spark.sql.execution.datasources.orc.OrcFilters$.buildLeafSearchArgument(OrcFilters.scala:229)
```

### Does this PR introduce any user-facing change?
Yes

### How was this patch tested?
Added tests to `OrcFilterSuite`.

Closes #28261 from MaxGekk/orc-date-filter-pushdown.

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.
