refactor(tests-async): unify duplicated tokio runtime bridges

11 downloader/installer integration-test files each redefined an
identical current_thread `run()` helper to block on async code. Extract
one shared multi_thread Runtime into tests/common/async_runtime.rs so
concurrent #[test] threads can all block_on it, matching the direction
item 7 (top-level Runtime) will take in production code.
