Feat: add initial Google Drive connector support (#11147)

### What problem does this PR solve?

This feature is primarily ported from the
[Onyx](https://github.com/onyx-dot-app/onyx) project with necessary
modifications. Thanks for such a brilliant project.

Minor: consistently use `google_drive` rather than `google_driver`.
