6104: Adding parameters API: measure_iteration r=hkaiser a=hkaiser

- split `get_chunk_size` CP into `measure_iteration` and modified `get_chunk_size`
- introducing a breaking change to `get_chunk_size` and `processing_units_count` customization point, those now expect the time for one iteration

The new APIs are:
```
    template <typename Target, typename F>
    hpx::chrono::steady_duration measure_iteration(
        Target&&, F&&, std::size_t num_tasks);

    template <typename Target>
    std::size_t processing_units_count(
        Target&&, hpx::chrono::steady_duration const&, std::size_t num_tasks);

    template <typename Target>
    std::size_t get_chunk_size(Target&&,
        hpx::chrono::steady_duration const&, std::size_t num_cores,
        std::size_t num_tasks);
```
This also moves all executor parameter objects to `namespace hpx::execution::experimental`.
