Refactor asset copying in CMake configuration for yaze target

- Removed the custom target for copying assets and integrated post-build commands directly into the yaze target.
- Updated commands to create necessary directories and copy asset files (fonts, themes, layouts, libraries) to the output directory, streamlining the build process for Windows and Linux.
