chore(ci): disable on draft pull requests

As draft PRs are explicitly in a state which is not ready to be merged,
there is no need to run the full suite of CI workflows every time there
is an update. In particular, this commit disables:

- Cirrus workflows, as Cirrus has a minute quota
- Wheel builds
- Long-running tests

The test matrix is _still_ being run.
