RFR: 8292596: Make SymbolHashMap a ResourceHashtable

Thu Aug 18 11:50:00 UTC 2022

Please review this straightforward change to use ResourceHashtable for SymbolHashMap, which is used by the Class File Reconstituter.  The table maps Symbol* to constant pool indices for loaded classes (Symbol refcounting unnecessary as the class is not unloaded because it's in use).
Tested with jvmti tests locally and tier 1-3.
