Suppress manykeys test on duplicate key ids [v9_16]
requested to merge 3525-key-id-clashes-across-algorithms-cause-problems-with-statistics-v9_18-v9_16 into v9_16
If there are duplicate key ids across multiple algorithms expected output is no met. We have fixed this in on main but decided to not back port the fix as it will change the statistics channel output.
This change detects when there are duplicate key id across algorithms as skips the sub test.
