### What changes were proposed in this pull request? Use Files.createDirectory() to create local directory instead of File.mkdir() in DiskBlockManager. Many times, we will see such error log information like "Failed to create local dir in xxxxxx". But there is no clear information indicating why the directory creation failed. When Files.createDirectory() fails to create a local directory, it can give specific error information for subsequent troubleshooting(also throws IOException). ### Why are the changes needed? Throw clear error message when creating directory fails. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? `DiskBlockManagerSuite` Closes #28997 from sidedoorleftroad/SPARK-32172.
