Use Case

As a driver engineer,
I want the auto encrypter type and accessor to be private in the driver,
So that so that we are not publicly exposing a private type from our FLE bindings.

User Impact

Users will no longer be able to access the AutoEncrypter interface or the auto encrypter from an encrypted MongoClient.
