RFR: 8305080: Remove finalize() from test/hotspot/jtreg/compiler/jvmci/common/testcases that used in compiler/jvmci/compilerToVM/ tests

[Afshin Zafari]

The finalize() methods are removed and replaced by Cleaner callbacks.

Note:
`test/hotspot/jtreg/compiler/jvmci/compilerToVM/HasFinalizableSubclassTest.java` may be removed since there is no need to test if finalize() exists in the subclasses or not..
