Fix compilation error in Thermal Runaway debugging code

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.

- Search all symbols and apply prefixes where needed
- Encapsulate some private methods
- Inline some setters
- Make `microstep_mode` a public method

Fix for PR #3526(Configuration.h LCD & SDCard section rewrite)

It removes duplicated BQ_LCD_SMART_CONTROLLER.

Additional follow-up the PR #3631(Encapsulate Stepper, Planner, Endstops in singleton classes)

・Change from abort_on_endstop_hit to stepper.abort_on_endstop_hit in endstop.cpp, Marlin_main.cpp, and ultralcd.cpp
・Add include path to cardreader.h and temperature.h in endstop.cpp(for CardReader class and disable_all_heaters())
It fix compilation error when ABORT_ON_ENDSTOP_HIT_FEATURE_ENABLED and SDSUPPORT are enabled.

・Change from digipot_current() to stepper.digipot_current() in Marlin_main.cpp
・Change from digitalPotWrite() to stepper.digitalPotWrite() in Marlin_main.cpp
It fix compilation errors when HAS_DIGIPOTSS is enabled.

・Change from microstep_mode() to stepper.microstep_mode() in Marlin_main.cpp
・Change attribute of microstep_mode() from private to public in stepper.h
・Change from microstep_readings() to stepper.microstep_readings() in Marlin_main.cpp
・Change from microstep_ms() to stepper.microstep_ms() in Marlin_main.
It fix compilation errors when HAS_MICROSTEPS is enabled.

Fix for #6 3593, #3648
this time excludung 'DEL' instead of accidently '~'.

Follow-up the PR #3631(Encapsulate Stepper, Planner, Endstops in singleton classes)

It fix compilation error when ADVANCED_OK is enabled

Some clean-up for example configuration files

Follow-up and fix the PR #3253(Make the Autotune item(s) in the LCD menu optional):
・Update forgotten file(Felix/Configuration_DUAL.h)

Follow-up the PR #3526(Configuration.h LCD & SDCard section rewrite):
・Add section of RigidBot Panel to RepRapWorld/Megatronics/Configuration.h

Follow-up the PR #3576(Z Safe Homing for all):
・Adjust spacing

Follow-up and fix the PR #3625(Print job statistics):
・Update forgotten file(Felix/Configuration_DUAL.h)
・Remove ambiguous character "f" in top of RigidBot/Configuration.h

The character 0x7E is common in 8.3 filenames. Maybe the last condition
should be removed completely instead.
