Recompose linear operator during serialization (#3621)

Summary:
Pull Request resolved: https://github.com/pytorch/executorch/pull/3621

As title.

Introduce a pass to reconstruct linear. This allows us to add `permute` and `addmm` to the partitioner list since `linear` will be recomposed and is now supported in the backend.
