    search: copy result to clipboard if requested
    
    Some search providers such as GNOME Characters want to copy search
    results to clipboard.  However, on Wayland, clipboards are only
    accessible from applications that have a visible surface on display.
    
    This patch allows a search provider to request the shell to copy a
    search result to clipboard when 'clipboardText' is included in the meta
    of the result.
