Add container build jobs to all build workflows (#190)

Add container build jobs alongside the existing wheel jobs. Tag
containers based on which workflow was triggered.

Tags:
* PR: `pr-{{ github.event.number }}` ~`{{ github.sha }}`~
* Nightly: `nightly` ~`{{ github.sha }}`~
* Release candidate: `latest` ~`{{ github.sha }}`~
* Release:  `latest` `stable` ~`{{ github.sha }}`~

Edit: To save space, don't use unique tags.

- - -

* Tag RC and releases with their versions. (e.g. 0.3.0-rc, 0.3.0)
* Reuse wheel builds in container
