8283276: java/io/ObjectStreamClass/ObjectStreamClassCaching.java fails with various GCs

[satyenme]

Backporting JDK-8283276: java/io/ObjectStreamClass/ObjectStreamClassCaching.java fails with various GCs. Adjusting test to be compatible with GCs other than G1. Ran GHA Sanity Checks, local Tier 1 and 2, and adjusted test directly. Patch is nearly clean: since Reference.refersTo is not supported, needs minor adjustments.

Taking a closer look at the history, seeing this commit when initially backporting the test. Planning to adjust to not use Reference.refersTo (which JDK 11 doesn't directly support), rerun local tests and add another commit here.
