Remove wal_sync_method=fsync_writethrough on Windows.
The "fsync" level already flushes drive write caches on Windows (as does
"fdatasync"), so it only confuses matters to have an apparently higher
level that isn't actually different at all.
That leaves "fsync_writethrough" only for macOS, where it actually does
something different.
