Niels Lohmann f3768d6868 Match ABI tag order in namespace tests to abi_macros.hpp (#5551)
* Match ABI tag order in namespace tests to abi_macros.hpp

NLOHMANN_JSON_ABI_TAGS concatenates the tags as _diag, _ldvcmp, _dp,
but the default and noversion ABI tests expected _diag, _dp, _ldvcmp.
The tests therefore failed whenever both JSON_DIAGNOSTIC_POSITIONS and
JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON were enabled, a combination
CI never exercises. Reorder the expectations to match the header.

Also document the _dp tag in the namespace feature page, which listed
only _diag and _ldvcmp.

* 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.
