Max Gekk 84bf07bbd7 [SPARK-33878][SQL][TESTS] Fix resolving of spark_catalog in v1 Hive catalog tests 
### What changes were proposed in this pull request?
1. Recognize `spark_catalog` as the default session catalog in the checks of `TestHiveQueryExecution`.
2. Move v2 and v1 in-memory catalog test `"SPARK-33305: DROP TABLE should also invalidate cache"` to the common trait `command/DropTableSuiteBase`, and run it with v1 Hive external catalog.

### Why are the changes needed?
To run In-memory catalog tests in Hive catalog.

### Does this PR introduce _any_ user-facing change?
No, the changes influence only on tests.

### How was this patch tested?
By running the affected test suites for `DROP TABLE`:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *DropTableSuite"
```

Closes #30883 from MaxGekk/fix-spark_catalog-hive-tests.

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.
