Also improve the documentation of this and related options, and set
EXTRUDE_MINTEMP to 170 everywhere.

`FORCE_INLINE` seems to have no effect on code generation with standard
optimization.

So that `ultralcd.cpp` doesn’t need to worry about the details.

Follow-up the PR #3643(Temperature singleton)

・Change from fanSpeedSoftPwm[0] to thermalManager.fanSpeedSoftPwm[0] in planner.cpp
It fix compilation error when FAN_SOFT_PWM is enabled.

・Remove declaration of setExtruderAutoFanState() in temperature.h
Because that function was abolished.

・Change from babystepsTodo to thermalManager.babystepsTodo in ultralcd.cpp
It fix compilation errors when BABYSTEPPING is enabled.

When setting the bed temp via M140/M190 if the thermistor does not read an increase of WATCH_BED_TEMP_INCREASE degrees by WATCH_BED_TEMP_PERIOD seconds then it will throw "Error:Heating failed, system stopped! Heater_ID: bed" and call the kill() function.

Conflicts:
	Marlin/Configuration_adv.h

As noted by @FalloutBe in #3519

Following up on #3231

Fixes for #3189

Setting a temp is still missing

Adds the parameter U to M303. If U1 is included , it will use the
PID-values from the auto-tune.

Keep "astyled" reformatting

Apply `ENABLED` / `DISABLED` macros to temperature-related files.

to warrant watching is set or reset.

Make setTargetBed() in _lcd_preheat() dependant of TEMP_SENSOR_BED.
Use disable_all_heaters() in lcd_cooldown() and abort_on_endstop_hit.

- Make thermal protection for all hotends and/or bed into simple
switches
- Now enable `WATCH_TEMP_PERIOD` when `THERMAL_PROTECTION_HOTENDS` is
enabled
- Move detailed thermal parameters to `Configuration_adv.h`
- Add sanity checks to warn about old configurations
- Change `WATCH_TEMP_PERIOD` to seconds instead of milliseconds

- Add comments documenting `thermal_runaway_protection`
- Add an enum for the thermal runaway states
- Add macros for temperature helper functions
- Fix a glitch with the z probe sled in homeaxis

cardreader.cpp needs temperature.h for autotempShutdown() when
AUTOTEMP is defined but warns about unused variables.
Unpublished variables by putting them in to temperature.cpp.

- Reduce calls to millis()
- General cleanup of manage_heaters
- General cleanup of pid autotune
- Formatting here & there
- Macros to clean up and shrink ISR code (reduced by ~364 lines)
