Summary: CMICmdArgSet stores a vector of non-const pointers to the arguments that it is validating. It owns them and is responsible for deleting them. We don't need to pass a const reference to the argument to CMICmdArgSet::Add and then take the address and const_cast it when we can just pass the argument pointer in directly. This lets us remove some noise at every call site for CMICmdArgSet::Add and then clean up a couple of bits inside CMICmdArgSet to remove const_casts.
