Review comment:
It seems that we have more than 3 places using a long method chain to
create the field logical types. I think we can provide a new constructor for
EqualiserCodeGenerator to accepting `RowType`. This can simplify code and
improve readabliity. E.g.
```scala
def this(rowType: RowType) = {
this(rowType.getChildren.asScala.toArray)
}
```

Review comment:
nit: We can put this member variable into parant class
`DeduplicateFunctionBase`, this variable is used by multiple classes.

Review comment:
Please use a more suitable method name for this test, this method name
sounds same with the above one `testWithGenerateUpdateBefore`. What do you
think about `testWithStateTtlDisabled`.
