Add DFU runtime and mode "class"
With the runtime and mode portions in separate classes, a single application should only be building with one or the other enabled. In some applications both might be desired at build time. The CFG_TUD_DFU_RUNTIME_AND_MODE option creates a DFU class, which asks the application which mode to initialize to. This allows a runtime change between RT and DFU mode, by just reinitializing tusb.
