Add missing Catalyst conversions #971
Description
Add the last missing operation Conversions between Catalyst and MQTOpt.
I know that I noted that in the other PR with the conversions already, but most of these actually have an equivalent in Catalyst.
And I also believe it is very much desirable that we can translate all quantum gates back and forth. Otherwise, we will always be stuck with a mixture of dialects, which will almost surely hinder optimizations.
Nothing to be tackled in this PR, but definitely in a direct follow-up.
