crypto: hash - Remove support for cloning hash tfms
Hash transformation cloning no longer has a user, and there's a good
chance no new one will appear because the library API solves the problem
in a much simpler and more efficient way. Remove support for it.
Note that no tests need to be removed, as this feature had no tests.
