rename to portable build and bundle XRT/XDNA libraries

- Rename FLM_STATIC_BUILD to FLM_PORTABLE_BUILD for clarity
- Link XRT dynamically (not statically) to avoid uuid dependency issues
- Link FFmpeg statically (built from source) for portability
- Bundle XRT and XDNA .so files with distribution using file(GLOB)
- Update preset from linux-static to linux-portable
- Update workflow to verify portable build

This creates a portable distribution with:
- Static FFmpeg (no external FFmpeg deps)
- Dynamic XRT bundled in lib/ directory
- RPATH set to $ORIGIN/../lib for automatic discovery
