Refactor Live2D plugin and renderer for improved clarity and performance

- Updated EGL and OpenGL ES integration in gl.rs for better context management.
- Simplified error handling and logging in model.rs and plugin.rs.
- Enhanced texture handling and rendering logic in renderer.rs.
- Added a script to find Cargo configuration files for easier debugging.
- Removed unused imports and dead code to clean up the codebase.
