RFR: 8302815 Use new Math.clamp method in core libraries

Sat Feb 18 10:58:10 UTC 2023

For cleanup and dogfooding the new method, it would be nice to use Math.clamp where possible in java.base. See PR #12428.

As Math.clamp performs an additional check that min is not greater than max, I conservatively replaced only those occurrences where I can see that this invariant is always held. There are more occurrences, where clamp can be potentially used but it's unclear whether min <= max is always true.
