    meson: Add a fallback for the harfbuzz dependency
    
    This meson port is not upstream yet, so a wrap file is not included.
    Upstream has expressed interest but the port hasn't been tested on all
    platforms yet. Will be added when it gets upstreamed.
    
    Link to WIP port: https://github.com/centricular/harfbuzz
