### What changes were proposed in this pull request? * Unify the create table syntax in the parser by merging Hive and DataSource clauses * Add `SerdeInfo` and `external` boolean to statement plans and update AstBuilder to produce them * Add conversion from create statement plan to v1 create plans in ResolveSessionCatalog * Support new statement clauses in ResolveCatalogs conversion to v2 create plans * Remove SparkSqlParser rules for Hive syntax * Add "option." namespace to distinguish SERDEPROPERTIES and OPTIONS in table properties ### Why are the changes needed? * Current behavior is confusing. * A way to pass the Hive create options to DSv2 is needed for a Hive source. ### Does this PR introduce any user-facing change? Not by default, but v2 sources will be able to handle STORED AS and other Hive clauses. ### How was this patch tested? Existing tests validate there are no behavior changes. Update unit tests for using a statement plan for Hive create syntax: * Move create tests from spark-sql DDLParserSuite into PlanResolutionSuite * Add parser tests to spark-catalyst DDLParserSuite Closes #28026 from rdblue/unify-create-table.
