[fx minimizer] Add an option to minimizer to allow return all intermediate results (#57279)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57279
Added an option "return_intermediate". If true, when building the submodule we want to run , we will replace the output with all the nodes, so that intermediate results of all the nodes will be returned as output.
This is recommended to use with `run_node()` function.
Test Plan: `buck test glow/fb/nnpi/lowering:net_min_tests`
