Use 5°C threshold to be consistant with other parts
of the firmware.
Relying on 95% of the target temperature creates
a dependency on the temperature:
PLA: Target = 215°C, threshold = 10.75°C
PETG: Target = 230°C, threshold = 11.5°C
ABS: Target = 255°C, threshold = 12.75°C
ASA: Target =260°C, threshold = 13.0°C
PC: Target = 275°C, threshold = 13.75°C
My proposal is we instead use a constant
TEMP_HYSTERESIS = 5, which is consistent with
M109, and behavior when restoring print from RAM
and some of the MMU code (like unload function)

This commit adds the ability for the firmware to dim and wake the
backlight when LCD updates are disabled. Such as in the MMU error screen
or when rendering full screen messages which typically
disable the LCD updates to prevent the status screen from rendering.

It may be useful to view the Sensors menu
while the toolchange loading test is taking
place. For example to see if the reading is flickering
The firmware needs to call lcd_update(0) to update the screen rendering.

Model UV as power-invariant, so that scaling P doesn't change the
intercept location (that is, the zero point remains at the same
temperature even for more powerful heaters).
NOTE: It's not clear to me whether this is generally true (couldn't
find a datasheet from the same heater in diffent power variants
showing the efficiency loss)
- Expose TEMP_MODEL_fS and TEMP_MODEL_LAG as D and L respectively,
initializing the default values based on the previous hard-coded
values.
- Always round L to the effective sample lag to future-proof model
upgrades or changes (the stored value _is_ the effective value).
- Introduce UV as a new linear term for PTC heaters, defaulting
to an identity for model backward-compatibility.
On printers without the MMU no error screen should occur and no attempts of communication with the MMU should be performed -> EEPROM_MMU_ENABLED should default to 0.
PFW-1418
Use "echo:" for thermal model error reporting to avoid octoprint
automatically sending a M112 kill.
Keep using "error:" instead for other thermal errors (MAXTEMP/etc).
This should allow resuming a thermal mode pause with the default
octoprint settings.
This is an 80% solution to PFW-1488 which should be somewhat compatible with the existing languages/translations infrastructure.
I don't see a point in extending the infrastructure a great deal to support some compile-time replacement in order to patch just MSG_DESC_FW_UPDATE_NEEDED.

The general idea is to keep platform specific implementation away from the MMU state machines as much as we can.
That would enable unit testing the top level MMU state machine and integration into other project as well (if needed).
The function adds a bit of overhead compared to code_value()
I suspect this function is a relic of the past.

During calibration model warnings are possible/normal. This is
apparently leading some into thinking the hotend might be faulty
and abort the calibration with a hard reset.
Disable warnings/beeps during calibration.
Rely on the error threshold only.
It may seem counterintuitive to disable the E-motor, but it gets enabled in the planner whenever the E-motor is to move.
The idea behind disbling the E-motor when it won't be needed for some time is to save power and lower the heat of the motor.
Therefore it is especially important to disable the motor before the printer pauses a print due to some MMU error screen.
Used lcd_print_pad_P is some obvious places. We can probably use
this function in more places to further save flash memory

Because this error is not an MMU error but a printer one, the existing infrastructure has been bent to support such a scenario.
During testing it turned out, that some machines fail to draw the error screen due to previous internal states.
This PR resets the internal states so that the conditions for drawing the error screen are met.
During thermal errors all fans are set to full speed.
When the print is resumed or stopped *and* the thermal error is gone,
also restore the autofan state.
