Skip reading file size if path name is too long

[twilight39]

Description

The Python os.stat() function below throws an unhandled OSError exception if the file being read's path length exceeds what the OS allows (e.g. 255 on Win7, 1024 on Mac).

	try:
	stat = os.stat(file_path)
	if stat.st_ino not in seen: # Visit each file only once
	# this won't add the size of a hardlinked file
	seen.add(stat.st_ino)
	if not is_excluded:
	data_size_filtered += stat.st_size
	seen_filtered.add(stat.st_ino)
	except (FileNotFoundError, PermissionError):
	continue

Motivation and Context

Currently, the whole application will crash when estimating backup size if a single file (even if it's excluded) exceeds the maximum length allowed by the OS. PR #2206 addresses excluding files from being calculated as part of the backup size, and this PR ignores files that have an excessive path length.

How Has This Been Tested?

I've run the pytest and pre-commit tests and they have passed.
I'm unable to manually test this as MacOS will not allow me to create a file with a path length exceeding 1024.
