Add initial automated release build workflow

Provide workflow used to automate the creation of GitHub releases upon
pushing a tag. The "upstream" workflow imported by this one applies
conditional logic (based on tag name) to determine whether a stable or
pre-release GitHub release is created.

By default, release assets are generated and provided by the release.
Library projects explicitly forgo the explicit generation of release
assets.
