[ETFeeder] Update attrs to optional

[changhai0109]

Summary

For those optional attrs in chakra schema, we introduce std::optional to store attr fields, which can be used to indicate whether a attr exists or not. Also add helper functions to check if has this attr, also try_get with default values.

Test Plan

# setup codes
git clone git@github.com:changhai0109/astra-sim.git astra-sim
cd astra-sim
git checkout changhai-improve-workload-layer
git submodule update --init --recursive
cd extern/graph/chakra
git remote add folk git@github.com:changhai0109/chakra.git
git fetch folk && git checkout changhai-improve-workload-layer
cd ../../..

# at astra-sim dir
bash build/astra_analytical/build.sh 
cd runs/example/workload
bash downlaod.sh
cd ..
bash run.sh

Then have output:
