Treat all keys as DialogKey instead of CmdKey
We previously treated all keys as a CmdKey to fix double characters when entering text in Terraria.
Secrets of Grindea uses InputKey to trigger TranslateMessage, but InputKey is called after CmdKey, so treating all keys as CmdKey breaks it.
DialogKey is called after InputKey, so this fixes both Secrets of Grindea and Terraria.
