json_sax_dom_parser and json_sax_dom_callback_parser each had a private copy of handle_diagnostic_positions_for_json_value(), identical except for comments. Move the body into one static member function, detail::diagnostic_positions::set_from_lexer(value, lexer), which both classes call with their lexer pointer. basic_json befriends the new struct (only when JSON_DIAGNOSTIC_POSITIONS is enabled), as the position members are private. The discarded case is reached through the callback parser, so the LCOV_EXCL markers that only the dom parser's copy had are gone. The NOLINT on the unreachable default case loses the stray "-warnings-as-errors", which is not a check name. The start-position setup in start_object()/start_array() is left alone, as #5706 is editing the callback parser's versions. Behavior, the public API and the ABI are unchanged.
