Combine thermal runaway and watch-period

Browse Source 
- 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

This is a feature to protect your printer from burn up in flames if it has
a thermistor coming off place (this happened to a friend of mine recently and
motivated me writing this feature).
The issue: If a thermistor come off, it will read a lower temperature than actual.
The system will turn the heater on forever, burning up the filament and anything
else around.
After the temperature reaches the target for the first time, this feature will
start measuring for how long the current temperature stays below the target
minus _HYSTERESIS (set_temperature - THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).
If it stays longer than _PERIOD, it means the thermistor temperature
cannot catch up with the target, so something *may be* wrong. Then, to be on the
safe side, the system will he halt.
Bear in mind the count down will just start AFTER the first time the
thermistor temperature is over the target, so you will have no problem if
your extruder heater takes 2 minutes to hit the target on heating.

* Thermal Runaway Protection protects your printer from damage and fire if a
* thermistor falls out or temperature sensors fail in any way.
*
* The issue: If a thermistor falls out or a temperature sensor fails,
* Marlin can no longer sense the actual temperature. Since a disconnected
* thermistor reads as a low temperature, the firmware will keep the heater on.
*
* The solution: Once the temperature reaches the target, start observing.
* If the temperature stays too far below the target (hysteresis) for too long,
* the firmware will halt as a safety precaution.
