fixes #2487

This pass is intended to drop the FHE part and just run in plaintext, and so all mgmt ops can be safely deleted. This can result in empty secret.generic ops (just with a yield) and so an extra branch is added to an existing pattern to handle removing those.

This PR was mostly Gemini, with minor manual tweaks
