Revert "fs: Remove NTFS classic"

This reverts commit 7ffa8f3d30. Reverts the removal of the classic read-only ntfs driver to serve as the base for a new read-write ntfs implementation. If we stack changes on top of the revert patch, It will significantly reduce the diff size, making the review easier. This revert intentionally excludes the restoration of Kconfig and Makefile. The Kconfig and Makefile will be added back in the final patch of this series, enabling the driver only after all features and improvements have been applied.
