Implement support for the --json= flag in the info subcommand (issue #38844). Previously, coredumpctl info always produced human-readable text output regardless of --json=. Add a CoredumpFields struct that holds all journal fields extracted for a coredump entry, along with coredump_fields_done() to release member resources and coredump_fields_load() to populate the struct from a journal entry. Both print_info() and the new print_info_json() use this shared loader, eliminating the duplicate RETRIEVE loop. print_info_json() builds a JSON object with the same fields shown by print_info(). Missing fields are omitted via SD_JSON_BUILD_PAIR_CONDITION, matching the tolerant behavior of print_info() rather than skipping the entry entirely. Signal/Reason handling mirrors print_info(): normal coredumps (MESSAGE_ID == SD_MESSAGE_COREDUMP_STR) emit a numeric Signal field; non-normal entries (kernel oops, etc.) emit a Reason field with the raw text from COREDUMP_SIGNAL.
