    Improve printing of pattern synonym types
    
    Add the function `pprPatSynType :: PatSyn -> SDoc` for printing pattern
    synonym types, and remove the ambiguous `patSynType` function. Also,
    the types in a `PatSyn` are now tidy.
    
    Haddock submodule updated to reflect the removal of `patSynType` by
    mpickering.
    
    Fixes: #11213.
