Move KeyList & InputHandler from game.h to client/inputhandler.h (#5752)

* Move KeyList & InputHandler from game.h to client/inputhandler.h

We have a header for inputs, move inputhandler class & related keylist object to it

Also introduce a cpp file for MyEventReceiver::OnEvent function in inputhandler.h because a so huge function doesn't needs to be inlined

* Pass clang-format on inputhandler.{cpp,h} (compatible)
