In this PR I propose to remove extra overloads of `operator()` in tests: - remove `enable_if` before `operator()` in test; - remove `enable_if` in the text empty `operator()` in test;...

Required to call `__parallel_for` through __internal::__except_handler

# Attention: ABI breaking change. Yet another approach to lazy `sycl::queue` creation in oneDPL hetero policies: - the source issue described at https://github.com/oneapi-src/oneDPL/issues/1060 - the previous approach has been implemented...

For example. please take a look at ```C++ template struct __brick_copy { // ... template void operator()(_ReferenceType1 __val, _ReferenceType2&&...

In this PR we implement empty source data support in async algorithms. For note: they are implemented as experimental for hetero policy only. The goal: to align oneDPL async algorithms...

Not all value checks using type epsilon as in the code ```C++ const auto eps = std::numeric_limits::epsilon(); __is_error = std::fabs(T(expected) - T(actual)) >= eps; ``` For example - `if (!(expected[k]...
