s_enclave_elrange_map destructor is invalid

In sdk/simulation/urtssim/enclave_creator_sim.cpp the declared destructor procedure is not guaranteed to run after std::map::~map due to the semantics of static objects. The value type is trivially copyable and destructible, so it doesn't need to be heap-allocated to begin with.

Start in sdk/simulation/urtssim/enclave_creator_sim.cpp and inspect the declaration and cleanup of s_enclave_elrange_map. Confirm how its current allocation interacts with std::map destruction, then make the storage and lifetime match the value type's trivial copy and destruction properties. Verify the simulator still builds and its relevant tests pass.
