.circleci: Fold postnightly workfow into nightly (#39669)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/39669
Folds the postnightly workflow, including html updating jobs and binary
size jobs, into the regular nightly workflow that should only run after
all upload jobs have completed.
This also moves the smoke testing jobs into the binary_builds workflow.
Do note that the devtoolset7 html update job has been removed since we
do not upload binaries specifically to that location anymore.
