STYLE: Use auto for variables initialized by New() in Examples

Replace initializations of the form `T::Pointer var = T::New()` (sometimes starting with `typename`) with `auto var = T::New()` in `Examples` to reduce code redundancy In accordance with C++ Core Guidelines, August 19, 2021: "ES.11: Use `auto` to avoid redundant repetition of type names" https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Res-auto Following PR #2826 and commit 828453d.
