[SPARK-33742][SQL] Throw PartitionsAlreadyExistException from HiveExternalCatalog.createPartitions() 
### What changes were proposed in this pull request?
Throw `PartitionsAlreadyExistException` from `createPartitions()` in Hive external catalog when a partition exists. Currently, `HiveExternalCatalog.createPartitions()` throws `AlreadyExistsException` wrapped by `AnalysisException`.

In the PR, I propose to catch `AlreadyExistsException` in `HiveClientImpl` and replace it by `PartitionsAlreadyExistException`.

### Why are the changes needed?
The behaviour of Hive external catalog deviates from V1/V2 in-memory catalogs that throw `PartitionsAlreadyExistException`. To improve user experience with Spark SQL, it would be better to throw the same exception.

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

### How was this patch tested?
By running existing test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableAddPartitionSuite"
```

Closes #30711 from MaxGekk/hive-partition-exception.

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.
