Add wal_sync_method=fdatasync for Windows.

Windows 10 gained support for flushing NTFS files with fdatasync()
semantics.  The main advantage over open_datasync (in Windows API terms
FILE_FLAG_WRITE_THROUGH) is that the latter does not flush SATA drive
caches.  The default setting is not changed, so users have to opt in to
this.
