[jdk19] RFR: 8289148: j.l.foreign.VaList::nextVarg call could throw IndexOutOfBoundsException or even crash the VM

[Jorn Vernee]

This patch changes all VaList implementations to throw `NoSuchElementException` when out of bounds reads occur on a VaList that is created using the Java builder API. The docs are updated accordingly.

For VaLists that are created from native addresses, we don't know their bounds, so we can not throw exceptions in that case.

Testing: `jdk_foreign` test suite on all platforms that implement VaList.
