Sean Owen c28a6fa511 [SPARK-29292][SQL][ML] Update rest of default modules (Hive, ML, etc) for Scala 2.13 compilation 
### What changes were proposed in this pull request?

Same as https://github.com/apache/spark/pull/29078 and https://github.com/apache/spark/pull/28971 . This makes the rest of the default modules (i.e. those you get without specifying `-Pyarn` etc) compile under Scala 2.13. It does not close the JIRA, as a result. this also of course does not demonstrate that tests pass yet in 2.13.

Note, this does not fix the `repl` module; that's separate.

### Why are the changes needed?

Eventually, we need to support a Scala 2.13 build, perhaps in Spark 3.1.

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

No

### How was this patch tested?

Existing tests. (2.13 was not tested; this is about getting it to compile without breaking 2.12)

Closes #29111 from srowen/SPARK-29292.3.

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.
