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.
