Add renderer.text_scaled() Lua binding

Browse Source 
lua_bindings.cpp:
- Added new lua_renderer_text_scaled() function
- Wraps renderer->draw_string_scaled() with proper scale support
- Registered as renderer.text_scaled(x, y, text, on, scale)
- Scale parameter defaults to 1 if omitted

Updated all 4 games to use text_scaled():
- simon_says.lua: All text now uses text_scaled with scale=2
- tic_tac_toe.lua: All text now uses text_scaled with scale=2
- memory_match.lua: All text now uses text_scaled with scale=2
- 2048.lua: All text now uses text_scaled with scale=2

This properly uses the C++ renderer's scaled text rendering instead of
workarounds in Lua, providing better performance and consistency.
