Removed commented-out template struct for pair.

Renamed the `KeyValue` template parameter to `sortable_t` to improve clarity and generality. Updated the `operator()` function to use `sortable_t` for the `data` parameter.

Refactored `LocalPasses<sortable_t, 1, Comparator>::operator()`

Introduced a new `bitonic_sort_config` structure with clearer naming and additional constants (`ElementsInShared`, `R`, `Batches`) for better readability and shared memory handling. Replaced old `BitonicSort` template specializations with modular helper functions (`atomicOpPairs`, `inThreadShuffleSortPairs`, `subgroupShuffleSortPairs`, `workgroupShuffleSortPairs`) to handle different stages of the sorting algorithm.

Added a `ShufflesSort` function to dynamically select shuffle/sort operations based on stride size. Refactored the `BitonicSort` structure to use the new modular functions, simplifying the `__call` method and improving the sorting logic.
