Extract C++17-only content from unit-items.cpp into its own test file

unit-items.cpp is a 1433-line file that was being compiled twice per CI configuration (once for C++11, once for C++17) purely because it contained a single, small JSON_HAS_CPP_17-gated SECTION ("structured bindings", 14 lines). Move that SECTION into a new, dedicated file (tests/src/unit-items-cpp17.cpp) so only that tiny file needs a second build; unit-items.cpp itself now builds/tests only once. No tests/CMakeLists.txt changes are needed since the existing file(GLOB ... src/unit-*.cpp) plus json_test_add_test_for() already auto-register and standard-gate any new unit-*.cpp file based on whether it textually contains JSON_HAS_CPP_<N> (the same mechanism already used for the existing unit-iterators3.cpp file, which follows the identical pattern). Verified with plain clang++ under -std=c++11/14/17/20 and via a local CMake configure+build that: - unit-items.cpp now only produces a test-items_cpp11 target (the former test-items_cpp17 target is gone) and its assertion/test-case counts are unchanged (2 test cases / 222 assertions) for every standard. - The new unit-items-cpp17.cpp produces test-items-cpp17_cpp11 (an intentionally empty translation unit under C++11 that reports 0 tests, 0 assertions, SUCCESS) and test-items-cpp17_cpp17 (1 test case / 1 assertion, identical to what "structured bindings" ran as before it was moved). Separately, unit-regression1.cpp (1530 lines) was also being built twice per CI configuration because it contained the substring JSON_HAS_CPP_17 -- but on inspection this was dead code: an orphaned "#ifdef JSON_HAS_CPP_17 / #include <variant> / #endif" left over from when the actual std::variant-based regression test (issue #1292) was relocated to unit-regression2.cpp. Nothing in unit-regression1.cpp uses <variant>, so there is no SECTION/TEST_CASE to preserve here; the dead include is simply removed. This was verified by grepping the file for any other use of "variant" (none) and confirming issue #1292 is still covered by unit-regression2.cpp. Compiled and ran under -std=c++11/14/17/20 and via CMake: unit-regression1.cpp now only produces a test-regression1_cpp11 target (test-regression1_cpp17 is gone) with an unchanged test-case count (3) under every standard.
