Linux: refine in-kernel NTFS driver selection

Keep the NTFS kernel-driver option as a generic in-kernel NTFS path rather than an ntfs3-specific path. Add --filesystem=kernel-ntfs and -m kernelntfs routes that select a registered or loadable kernel NTFS driver and mount with -i so mount.ntfs/ntfs-3g helpers are not invoked.

Preserve --filesystem=ntfs3 as a literal pin to the ntfs3 driver. Treat both ntfs3 and kernel-ntfs as mount-only selectors; volume creation continues to use filesystem type NTFS.

The preference and -m kernelntfs path only select an in-kernel NTFS driver when no explicit filesystem type was supplied and blkid detects NTFS.

Treat ntfs as the preferred in-kernel driver on Linux 7.1 and later, where the upstream read/write driver is expected. On earlier kernels, select ntfs only when module metadata identifies the standalone read/write driver and /sys/module confirms it loaded, avoiding ntfs3 read-only ntfs compatibility registrations. Fall back to ntfs3 otherwise, and report a generic kernel-driver error if neither supported driver is available or loadable.

Rename the internal preference/config field to MountNtfsWithKernelDriver, migrate the old MountNtfsWithNtfs3 preference key, and update UI strings, CLI help, documentation, release notes, and translation placeholders accordingly.
