For protocol version 2 of Queryable Encryption, the wire format of the FLE2IndexUpdatePayload has changed. The ECC token is removed, and the contentionFactor and serverDerivedFromDataToken fields are added. For each edge token sets, the ECC token is also replaced by the serverDerivedFromDataToken.
libmongocrypt must therefore start converting FLE2EncryptionPlaceholders for inserts/updates/findAndModifies to the new FLE2InsertUpdatePayloadV2 payload type.
