…esting library is in use. (#7577) **Explanation**: Allows swift-testing and XCTest to detect at runtime which testing library SwiftPM is trying to run so that they can adjust their behaviour (e.g. `XCTestScaffold`) appropriately. **Scope**: Test build products at runtime. **Risk**: Low. No obvious risk here to adding a new environment variable nobody is looking for. **Testing**: New unit test (tested at desk, but must be temporarily disabled in CI until CI is running a version of SwiftPM that includes the change.) **Original PR**: #7573
