Change Details

**Implementation notes** 1. Change `src/DataAccess/DonationExport/ExportQueryBuilder.php` to `JOIN` the tracking table, adding `campaign` and `keyword` fields. 2. Create a custom export field mapper in `src/DataAccess/ExportFieldMappers` that returns the field names in `getSQLFieldName`. The implementation of `getValueFromDbResult` returns either an empty string (when both fields are empty) or the `campaign` and `keyword` fields joined by a slash 3. Change entry for `tracking` in `src/DataAccess/DonationExport/DonationExportFieldCollection.php` from `LegacyDatabaseField` to a the new field mapper class.

NOTE: This is a technical subticket of {https://phabricator.wikimedia.org/T328075} This ticket is about changing export code to include the campaign and keywords in the database result instead getting them out of the legacy "data blob". **Affected repositories** - Fundraising Operation Center **Implementation notes** 1.
