**Explanation**: Existing `wasip1` triples for Embedded Swift already support concurrency, so this import should be implicit and no longer require package authors to make it explicit for Embedded Swift for WASI compatibility. **Scope**: limited to Embedded Swift for Wasm; **Risk**: low due to limited scope; **Testing**: added a new lit test that verifies the change. **Issue**: rdar://174021193
