"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.

I would think that this should behave similarly as when stopping
the print via the LCD.
Changed UnconditionalSto()p to not close the SD card file
if we're using Octoprint. Then there shouldnt be any file open.
Some of the variables which were not reset:
isPrintPaused
pause_time
saved_start_position
saved_printing_type
Bed heater may be left on?

For remote hosts, when the timer is stopped, then also save the statistics.
Slightly refactored save_statistics function by removing the parameters.
The function parameters are always the same.

I changed the code a bit so it would compile
in Prusa Firmware.
The paused duration is no longer included in the
print time statistics.

To handle power panic in M600 we started saving
relevant data at the start of M600 gcode.
We are currently also saving the same data within
gcode_M600 which is saved on the stack. I propose
we just use the data already saved in SRAM to reduce
stack usage.
