Add BPP format management and optimization features

- Introduced BPPFormatManager for handling various bitmap formats (2BPP, 3BPP, 4BPP, 8BPP) with conversion capabilities.
- Enhanced AtlasRenderer to support bitmap addition with BPP format optimization and added methods for optimized rendering.
- Implemented GraphicsOptimizer for analyzing and optimizing graphics sheets based on BPP formats, including memory and performance considerations.
- Developed BppFormatUI for user interface interactions related to BPP format selection and conversion previews.
- Integrated BPP format management into the canvas system, allowing for format selection and conversion within the GUI.
- Updated CMake configuration to include new source files related to BPP management and optimization.
