* Implement ClientEncryption::encryptExpression()
Define algorithm and query type constants for range preview
* Handle BSON encoding exceptions in encrypt/decrypt

* Define additional constants in mongocrypt-export.h
* PHPC-2104: ClientEncryption::QUERY_TYPE_EQUALITY is a string
Downstream change since MONGOC_ENCRYPT_QUERY_TYPE_EQUALITY was changed to a string type.
