save load path in state and pass to mosaicmllogger

What does this PR do?

Goal is to provide more visibility in the run life cycle. To do this, we can indicate when a run is resumed from checkpoint or not by displaying the load path if it was resumed from a checkpoint. Corresponding mcloud PR with mcli describe changes:
https://github.com/databricks-mosaic/mcloud/pull/4338

LGTM! Left a minor nit

Thanks for the PR! I'm hesitant about adding more public attributes to state. Is there something that already exists in state that we can do a before_load and after_load check on @eracah ?

Ethan and I discussed offline -- unfortunately i don' t think so because of the autoresume behavior... but open to ideas

[b-chu]

No idea unfortunately. I'm not blocking so feel free to merge
