chore: pytest-benchmark creates and loads all tables even if they aren't needed

In most cases when running th pytest-benchmark, we only run one function. The current code creates all of these tables for each of the three engines, regardless of whether the table or engine is used.

https://github.com/apache/sedona-db/blob/abcd1409bc35cb2ef7f69bbba708cbb6984720fc/benchmarks/test_bench_base.py#L30-L78

We create only the tables that are requested (e.g `polygon_simple`) and only for the engines that are requested (e.g DuckDB, SedonaDB, PostGIS). DuckDB and PostGIS aren't always used because they don't always support the function being benched.

Start in benchmarks/test_bench_base.py at lines 30-78 and inspect how pytest-benchmark selects functions, tables, and engines. Run the relevant benchmark setup to confirm the current behavior; done means only requested tables and engines are created and loaded, without preparing unused combinations.
