Optimize ICC profile embedding with copy_data=0

- Use copy_data=0 in WebPMuxSetImage and WebPMuxSetChunk to avoid unnecessary memory copies
- Ensure writer.mem and iccData remain valid until WebPMuxAssemble completes
- Release iccData only after WebPMuxAssemble finishes
- Clear writer memory as the final step

This reduces memory operations by 50% for images with ICC profiles.

Performance improvement:
- Before: Image data copied twice (SetImage copy + Assemble)
- After: Image data copied once (Assemble only)
- Benefit: ~50% reduction in memory operations for 1MB+ images
