GEODE-8217: Deserialize attribute before update and remove. (#5256)
When preferDeserializedForm is true we deserialize the previous attributes
before update or remove.
Deprecates preferDeserializedForm since when false it's unclear when you will
get serialized or unserialized forms of attributes.
(cherry picked from commit 9cc61bf2c0cb91f1a6b551fef6984214e23730e2)
> Geode session replication could leak internal serialized bytes during
