* Make parsing from std::istream and FILE* fast
Squashed onto develop cd6b428ef (CI fixes from #5860). Original commits:
- Let the lexer's bulk fast paths run on a window of the input
- Scan the get area of an input stream in bulk
- Lock a FILE once per parse instead of once per character
- Add benchmarks for parsing from a FILE* and for many values from a stream
- Avoid implicit unsigned char to char conversion in stream tests
- Make file_input_adapter::unlock() safe to call on a moved-from adapter

* Add ABI tags for JSON_DISABLE_STREAM_BULK_SCAN and JSON_DISABLE_UNLOCKED_FILE_IO
Both macros select between two definitions of an input adapter, so
translation units compiled with different settings violated the ODR when
linked together. Like the other ABI-affecting macros, they now append a
tag to the inline namespace: _dsbs and _dufio. Their defaults move to
abi_macros.hpp so that json_fwd.hpp sees them, and the natvis file is
regenerated for the new namespaces.

* Skip the exception-only checks of the stream input tests without exceptions

* 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.
