Max Gekk 26165427c7 [SPARK-31488][SQL] Support java.time.LocalDate in Parquet filter pushdown 
### What changes were proposed in this pull request?
1. Modified `ParquetFilters.valueCanMakeFilterOn()` to accept filters with `java.time.LocalDate` attributes.
2. Modified `ParquetFilters.dateToDays()` to support both types `java.sql.Date` and `java.time.LocalDate` in conversions to days.
3. Add implicit conversion from `LocalDate` to `Expression` (`Literal`).

### Why are the changes needed?
To support pushed down filters with `java.time.LocalDate` attributes. Before the changes, date filters are not pushed down to Parquet datasource when `spark.sql.datetime.java8API.enabled` is `true`.

### Does this PR introduce any user-facing change?
No

### How was this patch tested?
Added a test to `ParquetFilterSuite`

Closes #28259 from MaxGekk/parquet-filter-java8-date-time.

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.
