RFR: 8309673: Refactor ref_at methods in Serviceability ConstantPool

Thu Jun 8 22:01:11 UTC 2023

The accessor methods in constantpool.cpp were previously cleaned up to allow for different types of indices to be used, distinguishing them by the bytecode. This patch adds the same changes to the hotspot serviceability code. Verified with tier 1-5 tests.
