Updated renderer

Added Renderer_iface.h as a clean interface.
Replaced usages of old/ambiguous SDL calls in SDLRenderer.cpp to call SDL3 APIs: SDL_RenderTexture, SDL_RenderFillRect, SDL_RenderRect, SDL_RenderLine.
Converted copy() to call SDL_RenderTexture by converting integer rects to float rects.
Updated GameRenderer.cpp to include the new clean interface.
