feat(ComboWidget): add ability to have mapped inputs (#6585)

## Summary

1. Add a `getOptionLabel` option to `ComboWidget` so users of it can map
of custom labels to widget values. (e.g., `"My Photo" ->
"my_photo_1235.png"`).
2. Utilize this ability in Cloud environment to map user uploaded
filenames to their corresponding input asset.
3. Copious unit tests to make sure I didn't (AFAIK) break anything
during the refactoring portion of development.
4. Bonus: Scope model browser to only show in cloud distributions until
it's released elsewhere; should prevent some undesired UI behavior if a
user accidentally enables the assetAPI.

## Review Focus

Widget code: please double check the work there.
