Subject: [PATCH] [cDAC] Export interpreter JIT manager descriptor (#134190)

Expose `ExecutionManager::m_pInterpreterJitManager` as the optional
`InterpreterJitManagerAddress` cDAC data-descriptor global when CoreCLR
is built with `FEATURE_INTERPRETER`.

Will be used by #134072 for cDAC dump enumeration.
