Fix typo in Marlin_main.cpp

max_feedrate is in mm/s. line_to_destination needs a feedrate in mm/min because there is feedrate/60.

Fix for #1786

- Add comments documenting `thermal_runaway_protection`
- Add an enum for the thermal runaway states
- Add macros for temperature helper functions

Catch unlikely but possible error and head crash when using
Z_PROBE_REPEATABILITY_TEST

Fix MIN&MAX temperatures again

old bump_divisor for cartesian/corexy-printer

* Use "G29 S3 Xn Yn Zn.nn" to modify bad probed point manually
* Changed manual Z steps from 0.05 to 0.025 and made brought it to Configuration.h
