NIFI-12934 Clear Serialized Form of Records on Field Changes

Any time a Record's field is removed or renamed, ensure that we clear the 
Serialized Form so that a stale cached value cannot be written

This closes #8576

> When RenameRecordField runs, it updates the parent record for any matches. 
> However, when this happens, the Record's "serialized form" does not get 
> cleared. As a result, the Record Writer may (depending on its configuration) 
> write out the 'cached' / serialized form of the Record, resulting in no 
> change to the records.
