📖 [Story] Implement support for serde of TRT Graph modules with torch.export serde API

[peri044]

TL;DR

torch.export has serde API and now supports custom object (in our case torch.classes.tensorrt.Engine) serialization.

Goal(s)

We should be able to serialize/deserialize the output of torch-trt compilation.
