[FR] Add reverse sort of file names on SD

[vovodroid]

Is your feature request related to a problem? Please describe.

Currently files could be sorted by name, with option recent FAT entry first. So it could be difficult find new file.

Are you looking for hardware support?

No response

Describe the feature you want

Some slicers (at least Prusa) allows add date/time at the file name beginning like 202221028-174608. Reverse sort puts new file at the list top.

Additional context

Actually I built Marlin with such sort. Just changed

#define _SORT_CMP_NODIR() (strcasecmp(sortnames[o1], sortnames[o2]) > 0)
to
#define _SORT_CMP_NODIR() (strcasecmp(sortnames[o1], sortnames[o2]) < 0)
in Marlin/src/sd/cardreader.cpp

I can add config option and create PR if it seems reasonable.

Don't expect an answer. I suggest you to create PR anyway and wait
