ViewProperties: Store view properties in extended file attributes

Existing settings are converted.

Works on most FS except FAT/exFAT which fallback to .directory files.

If the extended file attributes (in ADS in Windows) can't be saved, they are saved to file as before.

BUG: 322922

You can see file xattr using for instance for Unix filesystems:

getfattr -d /home/meven
