Implemented task-based rendering and geometry stage buffers: 1. Get information about current frame objects 2. Accumulate geometry data into a stage buffer during frame rendering 3. Flush it to the GPU in single call 4. Run rendering process in post render stage https://github.com/thorvg/thorvg/issues/3489 https://github.com/thorvg/thorvg/issues/3455
