Add an internal-only helper StringAppendAndOverwrite() similar to
StringResizeAndOverwrite() but optimized for repeated appends, using
exponential growth to ensure amortized complexity of increasing
a string size by a small amount is O(1).

Use this function to replace STLStringResizeUninitializedAmortized()
