[Data] Simplify and consolidate progress bar outputs (ray-project#47692)

## Why are these changes needed?

Currently, the progress bar is pretty verbose because it is very
information dense. This PR:
- Reorganizes progress output to group by relevant concepts and
clarifies labels
- Standardizes global and operator-level progress bar outputs
- Removes the use of all emojis (poor rendering on some platforms /
external logging systems)

Will follow up with a docs PR once we merge this change, so that I don't
need to continuously modify the docs.

In the future, we should restructure the way progress bars are
grouped/tracked, so that we can tabulate the op-level progress bar
outputs.
