* M600 used 1°C threshold, which may increase the waiting time a bit
* Wizard used 3°C
Sync both to use TEMP_HYSTERESIS for consistancy
No change in memory footprint
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.

Flash: -26 bytes

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.
