Forward the three-argument FlexBuffers vector AppendToString helper to the formatting overload instead of calling itself. Adds typed and fixed-vector regressions; the original helper overflows the stack.

Tests: both C++ suites passed with strict mode and ASan/UBSan. Leak detection was disabled after reproducing an existing CrossNamespacePackTest leak with the unchanged upstream test source.
