Niels Lohmann 1bf0b1b6c2 Add the node index and scanning primitives of json_view (internal)
Internal parts of the zero-copy view (#5295), under detail/view and not
included by json.hpp, so that users of json.hpp compile nothing of it:

- macro_scope.hpp/macro_unscope.hpp: the few macros the view needs, under
  its own prefix (json.hpp undefines its own at its end); the throw macro
  honors JSON_NOEXCEPTION and JSON_THROW_USER like JSON_THROW
- string_ref.hpp: std::string_view from C++17 on, else a small stand-in
- node.hpp: the 16-byte node of the index; its kinds are value_t values
  (checked by a static_assert)
- document_data.hpp: the storage of a parsed document (node array, decode
  arena, owned input)
- scan.hpp: string and digit scanning with unrolled checks at fixed offsets
  (after yyjson) and the library's SWAR and UTF-8 checks, independent of the
  byte order
