Chen Lai 8c04593c0a [PyTorch Edge] Add backport to export old bytecode models (#56802)
Summary:
Add an api to backport a model vn to model vi. It accept an input model (file or buffer) and output a model (file or buffer) with an expected bytecode version.

In this change, the input is a model and it can come from a file or buffer. The output is a model and can be either file path or buffer.

When backport fails, function return false with a warning message :
```
/Users/chenlai/pytorch/cmake-build-debug/bin/test_jit --gtest_filter=LiteInterpreterTest.BackPortByteCodeModelV4:LiteInterpreterTest/*.BackPortByteCodeModelV4:*/LiteInterpreterTest.BackPortByteCodeModelV4/*:*/LiteInterpreterTest/*.BackPortByteCodeModelV4 --gtest_color=no
Testing started at 2:32 PM ...
CUDA not available. Disabling CUDA and MultiCUDA tests

[W backport.cpp:419] Warning: Backport doesn't support backport to version3 (function _backport_for_mobile_impl)
Process finished with exit code 0
```

## Test
1. Run both `caffe2/test/cpp/jit/test_lite_interpreter.cpp` and `caffe2/test/mobile/test_bytecode.py`.
2. Run all prod models with backport api.
