    Merge #1103
    
    1103: Lower AST::Visibility to HIR::Visibility properly r=CohenArthur a=CohenArthur
    
    Fixes #1093
    
    This should cover every case since the previous code simply created public HIR visibilities.
    
    The PR refactors the HIR::Visibility struct to be tinier and a desugared version of the AST one.
