ci: Improve testing and doc generation

- Remove use of `--examples`, we do not have examples
- Install drivers to $HOME
- Use YAML expansion to avoid repeating testing configs
- Make sure crates build with each feature set individually
- Add missing targets to cross-platform build step
- Check minimum version compatiblity with features _on_
- Gerate docs with "std" feature set
