RFR: 8357165: test java/lang/invoke/ClassValueTest.java fails intermittently [v2]

[Chen Liang]

> The test was originally written with product builds in mind; it didn't consider the slowness of debug builds, thus causing tests to fail.
> 
> Also there was a bug in testWeakAgainstClassValue: the test need to flush the backing map in the class to have the weak value removed. It is fixed in this patch as well.
> 
> Testing: ClassValueTest repeated 10 times on windows-x64/linux-x64/macosx-aarch64/linux-aarch64 fastdebug.
