RFR: JDK-8325496: Make TrimNativeHeapInterval a product switch

Mon Feb 12 09:17:09 UTC 2024

[JDK-8293114](https://bugs.openjdk.org/browse/JDK-8293114) introduced automatic C-heap trimming, for now supported only by the glibc. It is controlled by the command line switch `TrimNativeHeapInterval`. The feature has proven very valuable to customers, and all issues have been ironed out. So, I'd like to make this switch a non-experimental product switch.
