decouple from onedrive-support

decouple dependency on onedrive-support:

```
import {
editDistance, sanitizeName, splitByExtension,
} from '@adobe/helix-onedrive-support/utils';
import { StatusCodeError } from '@adobe/helix-onedrive-support';
```

but for that the utils above should be moved to helix-shared

Start by locating the imports from @adobe/helix-onedrive-support and the definitions of editDistance, sanitizeName, splitByExtension, and StatusCodeError. Review how helix-shared should provide the utilities; done means helix-google-support no longer depends on onedrive-support and its imports resolve from the intended shared package.
