Added sort_by_key algorithm for key-value sorting.
Improved performance of the reduce, min_element, max_element, minmax_element,
is_partitioned, and lexicographical_compare algorithms with DPC++ execution policies.
Improved performance of the reduce_by_segment, inclusive_scan_by_segment, and
exclusive_scan_by_segment algorithms for binary operators with known identities
when using DPC++ execution policies.
Added value_type to all views in oneapi::dpl::experimental::ranges.
Extended oneapi::dpl::experimental::ranges::sort to support projections applied to the range elements prior to comparison.

The minimally required CMake version is raised to 3.11 on Linux and 3.20 on Windows.
Added new CMake package oneDPLIntelLLVMConfig.cmake to resolve issues using CMake 3.20+ on Windows for icx and icx-cl.
Fixed an error in the sort and stable_sort algorithms when performing a descending sort
on signed numeric types with negative values.
Fixed an error in reduce_by_segment algorithm when a non-commutative predicate is used.
Fixed an error in sort and stable_sort algorithms for integral types wider than 4 bytes.
Fixed an error for some compilers where OpenMP or SYCL backend was selected by CMake scripts without full compiler support.

Incorrect results may be produced with in-place scans using unseq and par_unseq policies on
CPUs with the Intel® C++ Compiler 2021.8.

Improved sort algorithm performance for the arithmetic data types with std::less or std::greater comparison operator and DPC++ policy.

Fixed an error that caused segmentation faults in transform_reduce, minmax_element, and related algorithms when ran on CPU devices.
Fixed a compilation error in transform_reduce, minmax_element, and related algorithms on FPGAs.
Fixed permutation_iterator to support C-style array as a permutation map.
Fixed a radix-sort issue with 64-bit signed integer types.
