Update CircleCI to use Orb Default Baselibs and BCs

This PR updates the CircleCI config to default to using the Baselibs in
the CircleCI orb rather than explicitly specifying the versions. In most
cases, this is the "best" way as a change to the orb can fix this for
projects without the need for a PR.

Note that we keep commented the explicit anchors in case needed.
