Summary [JavaScriptCore] os_script_config_storage is not available when back-deploying

When back-deploying to downlevel builds from recent SDKs, the os_script_config_storage declaration is parsed as unavailable. We redeclare it in our code for older platforms, as a stub, but the compiler still treats it with the same unavailability.
