### Rationale for this change (See https://github.com/apache/arrow/issues/43694) ### What changes are included in this PR? Added the option `ExecContext exec_context` to `arrow::dataset::ScanOptions` and modified the scanner and sub-functions to either use the internally specified thread pool or the default internal pool when necessary. ### Are these changes tested? Added a Parquet scanner test that uses the new ExecContext using a separate thread pool for each fragment. ### Are there any user-facing changes? Yes, adds a new option. I'm not sure how to update the documentation though -- This is an automated message from the Apache Git Service.
