Issue:#46004
Context:
Initial changes resulted in merge conflicts. As a result,I had to
come up with a different approach since _SHARDED_SUFFIX is a tensor now.
Solution:
Add os.path.normpath function to _temp/part instead
Additional:

# Transformations:
# * Users pass in "save_path" in save() and restore(). Say "myckpt".
# * checkpoint_prefix gets fed <save_path><_SHARDED_SUFFIX>.
- #
+ # * If checkpoint_prefix is a S3 bucket path ".part" is appended to it
+ # * Otherwise _temp/part is appended which is normalized relative to the OS
# Example:
# During runtime, a temporary directory is first created, which contains
