#### PR Classification
This pull request introduces a new feature by adding support for documentdb_rum via index extensibility.

#### PR Summary
The changes integrate a new index access method for documentdb_rum, updating core indexing interfaces, schema definitions, and build/test scripts to enable extended RUM indexing functionality. Key updates include:
- **`internal/pg_documentdb_rum/src/documentdb_rum_adapter.c`**: Introduces the new `documentdb_extended_rum` handler with functions for scan, build, insert, and others.
- **`include/index_am/index_am_exports.h` and related utility files**: Add and update APIs for index extensibility (including multikey status support) to accommodate the new handler.
- **`pg_documentdb/src/index_am/create_indexes.c`**: Modifies index creation logic to use new opclass schemas and integrate the extended rum index handler.
- **SQL schema files (e.g., `documentdb_rum--1.0.sql` and operator class scripts)**: Define the new extension schema, operator classes, and functions required for extended RUM.
- **Build scripts and regression test files**: Update Makefiles and expected test outputs to load, build, and validate the documentdb_rum extension functionality.
