    devel/llvm-{cheri,morello}: reduce runtime dependencies
    
    Disable libedit and libxml2 dependencies as they have no obvious use.
    
    Disable the the perl and python runtime deps.  While we do install
    scripts that require these, most users of these ports will either use
    them on a full system where perl and python will end up installed or use
    them on a CHERI system were reducing bootstrap time is valuable.
