Move cibw config to pyproject.toml (#381)

Puts most `cibuildwheel` configuration into `pyproject.toml` instead of
using envvars in the github actions.

The rationale is that this makes it a little bit easier to build the
wheel locally for debugging and testing as there is less configuration
specific to GH actions

Note some of the envvars refer to GH action matrix items, so those
remain in the GH workflow.
