C++: mini_reflect: Add DefaultTypeTable (#4614)
* mini_reflect: Add DefaultTypeTable
Currently it's very easy to make a mistake when it comes to
instantiating the TypeTable to print a buffer because it is not type
safe.
This will allow us to write safer cpp code:
flatbuffers::FlatBufferToString(reinterpret_cast<const uint8_t *>(&t),
decltype(t)::DefaultTypeTable());
* c++: mini_reflect: update generated code
* Ensure types and names are set for mini_reflect
* c++: mini_refelct: update unit tests with new typed TypeTable
* Adding PR feedback of sylte and naming convention
