    Use sigPrec in more places in Convert and HsUtils
    
    Trac #16183 was caused by TH conversion (in `Convert`) not properly
    inserting parentheses around occurrences of explicit signatures where
    appropriate, such as in applications, function types, and type family
    equations. Solution: use `parenthesizeHsType sigPrec` in these
    places. While I was in town, I also updated `nlHsFunTy` to do the
    same thing.
