Niels Lohmann fd0ca40ea6 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.

Florian Albrechtskirchinger 39e27684ea Use DOCTEST_* compiler macros and suppress pragmas warning (#3550) 
Use DOCTEST_* macros in place of predefined compiler macros for compiler
detection and version checks.

The suppression of warning -Wrange-loop-construct in unit-items.cpp
