selectdevice returns MULTI:device in cumulative_throughput (#11367)

* selectdevice returns MULTI:device in cumulative_throughput

* load multi with throughput and disable cpu helper in cumulative

* disable cpu helper in cumulative_throughput

* add cumulative to bechmark_app help message

* modify benchmark_app.hpp clang-format

samples/cpp/benchmark_app/benchmark_app.hpp
