When building with GCC's -Wfinal-types, a lot of types of spdlog are marked as being more optimizable if they were marked final. This patch adds a possibility for the user of the library to `#define SPDLOG_FINAL final` and enjoy potentially better performance : GCC is then able to replace virtual calls by true function calls if it can ensure that there are no derived types). By default SPDLOG_FINAL is defined to nothing to not break existing code that may be inheriting of some of these types for some reason.
