.ci: Add nightly trigger, remove CircleCI linux binary builds (#70957)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/70957

Adds nightly trigger for github actions using a workflow that will pull
down viable/strict and tag it as `nightly` and then re-push it up to the
repository.

Also removes CircleCI linux binary builds since they will now be
outmoded in favor of our new GHA workflow
