[ci] Remove DevTools jobs from circleci build_and_test

Now that these run in GH, we can remove these jobs from the circleci
build_and_test workflow to speed up the remaining jobs left in circleci
since this was the long pole.

I have left the definition of these jobs in tact however, as they are
used for devtools_regression_tests which has yet to be migrated to GH.
