Subject: [PATCH] Test the ABI namespace with all ABI tags enabled

Build the default and noversion ABI config tests a second time with
JSON_DIAGNOSTICS, JSON_DIAGNOSTIC_POSITIONS and
JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON all set, so the expected tag
order is checked on every test run instead of depending on which CMake
options a CI job happens to enable.
