[C++] Require simdjson 4.3.0 for fractured_json APIs #51140
Description
Describe the bug, including details regarding any error messages, version, and platform.
Commit c8240bd introduced use of simdjson::fractured_json_options and simdjson::fractured_json_string (commit 06e3b9a later moved that).
These APIs are available starting with simdjson 4.3.0,
but ARROW_SIMDJSON_REQUIRED_VERSION is still set to 4.0.0
