* #2954: Provide std::conjunction and std::disjunction substitutes * #2954: Use conjunction and disjunction substitute to make formatter specializations for ranges and maps more robust (especially for Visual Studio compiler family) * #2954: As workaround for older MSVC compilers split formatter<std::filesystem::path> partial template specialization into two explicit specialization. * 2954: Add test case * Provide simplified implementations of conjunction and disjunction * Remove workaround explicit specializations if the partial specialization would cause an ambiguity error * Eliminate extra-test and merge it into existing std-test instead. Add conditionals for filesystem::path testing that does not run into the ambiguity problem.
