RFR: 8268427: Improve AlgorithmConstraints:checkAlgorithm performance [v4]

[Dongbo He]

> Now AlgorithmConstraints:checkAlgorithm uses List to check if an algorithm has been disabled. It is less efficient when there are more disabled elements in the list, we can use Set instead of List to speed up the search.
> 
> Patch contains a benchmark that can be run with `make test TEST="micro:java.security.AlgorithmConstraintsPermits"`.
