Summary: Removes the `RCTInstanceRuntimeDiagnosticFlags` getter and `RCTInstanceSetRuntimeDiagnosticFlags` setter (and the backing static) from the bridgeless `RCTInstance` runtime, on both the iOS and macOS platform copies. The setter had no callers anywhere, so the getter always returned an empty string and the `RN$DiagnosticFlags` JS global was never defined. The `ReactInstance::JSRuntimeFlags::runtimeDiagnosticFlags` field already defaults to an empty string, so the `initializeRuntime` call site now relies on that default with no change in runtime behavior.
