- No wait for heatup during host print recovery
- No extra Z lift when power panic happens during paused print
- added an extra EEPROM value
- fixed `EEPROM_LAST_ITEM`
- changed EEPROM version to 3.14.0
- Added `reset_uvlo` function
In the case of a Fan Error, the print is paused. If the nozzle is allowed to cool for a while before the print is stopped via the LCD, then the MMU will try to unload with a cold nozzle.
This can happen with ANY recoverable thermal errors.
In this commit I attempt to fix all scenarios. Including PFW-1544 where the nozzle is cooling down when the print has finished normally.

If the timer is expired, then the timer is stopped. This is OK since
we are starting the timer again anyway

When long moves are planned and executed the USB timer can expire.
In PrusaSlicer 2.7.1 the Toolchange command (T0, T1, etc.) is sent while the USB timer is expired. This will trigger
a manual MMU unload in the firmware. Not only does this trigger a loud beep from the buzzer, but this will also significantly increase print time.
The issue only affects host prints. SD card printing does not have this issue.
Fixes#4551
The fix in this commit is the following:
If there are blocks queued while printing via host AND the USB timer is halfway expired WHILE executing a move. Then simply restart the timer to keep it alive.

This function is not specific to power panic. Some printer models
do not have power panic enabled.
This change fixes a build failure

"PRUSA uvlo" is the last g-code to be processed after the power panic
recovery. For host prints, we want to finish processing all these
g-codes and put the print in a paused state.
Currently I am using lcd_pause_print() but this may be simplified
later.
A new PrinterState is introduced PowerPanicWaitingForHost to
differentiate this paused state from the typical paused state.
In this new paused state the printer is waiting for the host to boot up
and send M79.
Once M79 is seen a new action is sent "// action:uvlo_recovery_ready"
It is up to the host software to then resume the print correctly. All
the needed information to resume the print is in EEPROM and can
be read by using the D3 g-code.

If recover_print was never called, then there should be
no need to call lcd_setstatuspgm(MSG_WELCOME) since
the status line was not modified by the power panic feature.
