Minimal tests for memory usage contraints in partial-column read APIs

[itamarst]

Description

As follow-up to #15231, add memory usage tests for other APIs that allow reading a subset of columns from file, to ensure similar bugs to #15098 don't exist now or happen in the future.

• Write a memory usage test for read_avro partial column reads #15463
• Minimal tests for memory usage contraints in partial-column read_csv_* APIs #15374
• read_database
• read_delta
• Minimal memory usage tests for read_ipc read_ipc_stream #15479

I omitted Excel and ODS because those file types won't be that big in practice, and read_json/read_ndjson because you can't currently choose a subset of columns, so you're reading everything. Might still be optimizations one can do but this is more about #15098-style bugs where you load everything even though the user requested a single column.
