Support to load ONNX APIs based on JS runtime

[kallebysantos]

Hey there 🫡
I've been working withing supabase team on supabase/edge-runtime#368.
Since edge-runtime is based on short-live sandboxed workers, the use of transformers.js was very expensive due the model caching and session state. At this point the original proposal was to replace all the JS libraries like transformers.js to a embedded runtime backend by rust.

The Pipeline proposal

After some problems with enc/dec models I'd discuss with Supabase team, where @gregnr did the great suggestion of provide a more performative environment while keep using a well tested and maintained library like yours.

So we decided to move on it and export our custom ONNX runtime APIs to the edge-runtime environment, from the transformers.js side the only changed needed is to priority load the ONNX variable from globalThis. We'd follow the same API of onnxruntime-custom package so everything should work as expected.

The custom binding proposal

If you would like to test our runtime pls check my tranformers.js integration branch, at this file.
I also recommend to read the DEVELOPERS.md section to get more information about how to run the environment.
But basically just need to:

$ ./scripts/run_dind.sh

$ curl --request POST \
  --url http://localhost:9998/ort-rust-backend \
  --header 'Content-Type: application/json' \
  --data '{
	"input": [
		"one day I will see the world",
		"I will never forgive u"
	]
}'

Thanks for the PR and additional info! I've rebased to Transformers.js v3 and will ensure this is included in the next release of @huggingface/transformers.
