It's not clear to me why specializing nsCOMPtr<nsISupports> is
particularly useful, and this removes a lot of code, bringing us closer
to unifying nsCOMPtr and RefPtr.
The changes in other places are needed because we used to allow
nsCOMPtr<nsISupports> to implicitly coerce to nsISupports even for
rvalue references.

Which is not allowed for a good reason, generally.
