8336829: [lworld] serviceability/jvmti/RedefineClasses/RedefineLeakThrowable.java gets Metaspace OOM

[coleenp]

Run all versions of this test with -Xmx23m so that if CDS is off, the InMemoryCompiler will load without a Metaspace OOM. Also add a test to verify that new metadata created by inline/value classes are reclaimed, which I verified in gdb. Zeroed deallocated fields to help with manual verification.
Tested with jtreg/serviceability/jvmti/RedefineClasses tests.
