Add Set parameter in M78 Statistics gcode

[3d-gussner]

Often a full factory reset is the best way to solve some issues. But that also means that the statistics are lost and often user complain why we can't keep them.

This is an attempt to give the user the option to get the statistics AND restore them if needed.

Added new parameters to M78 to be able to restore statistics after a factory reset.
Also added the output to M503

Tested on MK404:

1. Connect via serial terminal
2. Open LCD Statistic menu
3. While printer is Idle send M78
   a. Example response when LCD Statistics menu shows 4.75m and 0d 2h 6m

Total filament:475 cm
Total print time:126 min

4. Simulate a print by sending M75 to start the print timer
5. On LCD it switches from Total filament and Total print time to Filament used and Print time
6. Send M78 after waiting at least 1 minute
   a. Example response when LCD Statistics menu show 0.00m and 0h 02m 05s

Filament used:0 cm
Print time:2 min

8. Send M77 to stop the print timer
9. The Statistics menu switches back to Total and you see the additional print time being added.
10. Send M503
    a. Example response in serial with total values being 4.75m and `0d 02h 08m

echo:Statistics:
echo:  M78 S475 T128

11. Perform Factory reset -> Statistics
12. Open again LCD -> Statistics menu
13. Send again M78 and you see

Total filament:0 cm
Total print time:0 min

14. Restore statistics using the output from M503
15. Example values: Send M78 S475 T128
16. On LCD you see the values being restored
17. Send M78 and also in serial output you see the restored values.

Thanks to @crabbedh for the request #3448 sorry it took so long to be implemented.

My only comment is there is some confusion between centimeter and meter.

I reviewed the filament usage SI units, and it looks like the EEPROM documentation was wrong. @3d-gussner you were right, the EEPROM value is in centimeters. 👍

There is one minor typo I found, but not a blocker.
