Title: Array.unique(): remove deprecated sort param, add optional test function [Ticket #2527901]

The sort parameter was deprecated back in 3.3.0, so it's time for it to go.

The optional test function makes it possible to perform custom comparison logic to determine whether two values should be considered equal.
