[pstl] Fix incorrect usage of std::invoke_result std::invoke_result takes function object type and arguments separately (unlike std::result_of) so, std::invoke_result_t<F()> usage is incorrect. On the other hand, we don't need std::invoke() semantics here at all. So just simplifying the code without extra dependency and use trailing return type as the fix.

Parallel STL is an implementation of the C++ standard library algorithms with support for execution policies, as specified in ISO/IEC 14882:2017 standard, commonly called C++17. The implementation also supports the unsequenced execution policy specified in Parallelism TS version 2 and proposed for the next version of the C++ standard in the C++ working group paper P1001. Parallel STL offers efficient support for both parallel and vectorized execution of algorithms. For sequential execution, it relies on an available implementation of the C++ standard library.
To use Parallel STL, you must have the following software installed:
unseq
and par_unseq
policies only have effect with compilers that support #pragma omp simd
or #pragma simd
