RFR: 8299858: [Metrics] Swap memory limit reported incorrectly when too large [v3]

[Severin Gehwolf]

> Please review this fix to [JDK-8292541](https://bugs.openjdk.org/browse/JDK-8292541) which adds the same handling for swap values exceeding what's possible in the non-container case. I.e. treats it as unlimited and fixes the reporting. This has been handled on the hotspot side similarly with [JDK-8292083](https://bugs.openjdk.org/browse/JDK-8292083).

> Testing:
> - [x] Container tests on linux x86_64 with cg v1
> - [x] Container tests on linux x86_64 with cg v2
> - [ ] GHA (seem to have had some infra issues, so re-running)
