Currently, Pause of an SD-Memory card print does not work.    This has been verified to resolve the issue by multiple people.   

I understand more work needs to be done to resolve some of the concerns...

- Fix a bug in MAXxxxx thermocouple temp reporting.
- Add support for 3-wire HD44780.
- Add support for PCA9533 RGB driver.
- Add configuration examples for FlashForge CreatorPro.

RemRam needs to redefine a particular timer to work correctly. The HAL did foresee this possibility and checks if the timer was already defined for either the stepper or temperature timer.

Prior to this commit the header file for the timers couldn't see those definitions in the pin file, but this commit will fix this.

Tested on an actual hardware to verify. (It wouldn't boot without it.)

- Use `TEST(dm,axis)` to determine directions instead of doing comparisons.
- Remove recomputation of `millimeters` and `delta_mm` since backlash compensation should not affect the distance over which material is extruded.

(Exactly matching the Azteeg X5 MINI Wifi)

* Add support for MKS Robin TFT display

- Add support for MKS Robin TFT display and encoder for MKS Robin board.
- Generic 128x64 UI with x2 upscale is used (for now).
- Tested on MKS Robin TFT V2.0 with ST7789V controller.

Move `watchdog_reset` from `.h` to `.cpp` to eliminate the need to include `MarlinConfig.h` in a HAL-related file.

* Make ExtUI respect MAXTEMP limits
  - Temperatures are now clamped by MAXTEMP limits rather than arbitrary values.
* Speed up USB init, add status
  - Speed up USB initialization
  - Show status message if init failed
* Enable status messages for EXTENSIBLE_UI
* Adjust max limit to MAX_TEMP - 15
* Misc. tweaks to formatting, const, etc.
