RFR: 8331950: Remove MemoryPoolMBean/isCollectionUsageThresholdExceeded from ZGC ProblemLists

Thu May 9 08:31:00 UTC 2024

Remove from zgc problemlists.

This was omitted when https://bugs.openjdk.org/browse/JDK-8303136 was integrated.

I see the tests passing, including with ZGC.  Just ran my own batch of tests in addition, and it includes passes with e.g. -XX:+UseZGC -XX:+ZGenerational
