The old user-facing TrialCheckpoint class has been deprecated in favor of `ray.ml.Checkpoint` and will be removed with this PR.
The main change in this PR is to delete the old `TrialCheckpoint` class and replace remaining API calls (e.g. `checkpoint.local_path`) with the correct AIR equivalents.
One issue that comes up is that with Ray client usage, checkpoint directories are not available on the local node (the client). Thus, we can't construct `Checkpoint` objects easily. (Previously, the TrialCheckpoint object held a reference to the location, even if it is not locally available). There are ongoing discussions on how to resolve this in the future. For now, we print an error when such a checkpoint is requested.
Depends on #25805

Update documentation to use `session.report`.
Next steps:
1. Update our internal caller to use `session.report`. Most importantly, CheckpointManager and DataParallelTrainer.
2. Update `get_trial_resources` to use PGF notions to incorporate the requirement of ResourceChangingScheduler. @Yard1
3. After 2 is done, change all `tune.get_trial_resources` to `session.get_trial_resources`
4. [internal implementation] remove special checkpoint handling logic from huggingface trainer. Optimize the flow for checkpoint conversion with `session.report`.
