Port upstream fix (PR#10736) to downstream v1 Lambda stream handler (#1047)

- **V2 Issue:** [Non-top-level server span created by Lambda
instrumentation](open-telemetry/opentelemetry-java-instrumentation#7808)

- **V2 PR:**
[#10736](open-telemetry/opentelemetry-java-instrumentation#10736)

The fix has been ported to v1 as a patch for non-stream handlers. This
change extends the fix to the stream handler in the v1 repository.

### Testing
- All unit tests pass.  
- End-to-end tests pass.  (with Java11, 17, and 21 runtime on Lambda)

### Backward Compatibility
- No risk of breaking existing functionality.  
- The change only adds instrumentation for `RequestStreamHandler`
without modifying existing behavior for `RequestHandler`.
- Existing users who do not use `RequestStreamHandler` remain
unaffected.
