    Remove ExnStr and ThrowsExn business
    
    In #14998, Item 1, we noticed that we could get rid of the last usage
    of `catchArgDmd` and did so in commit 00b8ecb.
    
    Since then, `catchArgDmd` has been dangling around in Demand.hs. This
    commit finally removes it and the resulting dead code involving `ExnStr`
    and `ThrowsExn`, which was the original concern of Item 1.
