Add frame tick system for continuous animation

- Added INPUT_FRAME_TICK event type to input_event.h
- Added wants_frame_updates() virtual method to Game base class
- Implemented frame tick logic in main loop (basic1.cpp and emulator/main.cpp)
- Added Lua bindings: game.set_frame_updates(bool) and INPUT.FRAME_TICK
- Updated LuaGame to support frame updates via registry flag
- Updated ball.lua to use continuous frame updates for smooth animation
- Both hardware and emulator now support continuous animation for physics/games
