[SYCL] Add key/value sorting and array input support in SYCL sorting algorithms

[againull]

TODOs before making ready for review:

• Fix issue with key/value sorting with array input for default sorter- for some reasons sorting is not stable, i.e. order of values is not preserved, even though default sorter does merge sort + bubble sort which are supposed to be stable.
• Implement is_blocked/is_striped as compile-time properties and add tests for them.
• Cleanup (traits, etc.)
