Summary

Process the command:

{"cleanupStructuredEncryptionData": "coll"}

Into:

{"cleanupStructuredEncryptionData": "coll", "compactionTokens": {...} }

That will permit users to use RunCommand to run the cleanupStructuredEncryptionData for the QEv2 protocol.

Background & Motivation

See Technical Design: Queryable Encryption Change the On-Disk Format and Wire Protocol for a description of this command.

See MONGOCRYPT-424 for the changes made for compactStructuredEncryptedData. I expect the changes for compactStructuredEncryptedData will be very similar to changes required for cleanupStructuredEncryptedData.
