### Description
Release OrtEnv before main function returns. Before this change, OrtEnv
is deleted when C/C++ runtime destructs all global variables in ONNX
Runtime's core framework.
The callstack is like this:
```

After this change, OrtEnv will be deleted before the main function
returns and nodejs is still alive.

Added pool/matmul/flatten ops
