Move dumpOpcodeStats() to jsi::Instrumentation, remove IHermesExtra (#53475)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53475

This is cleanup of IHermesExtra. Move the last method in IHermesExtra,
dumpOpcodeStats(), to jsi::Instrumentation, since other profile stats
dumping methods live in that interface as well.
