Encapsulate common display code in a singleton (#12395)
* Encapsulate common LCD code in a singleton
* Depend more UBL code on UBL_DEVEL_DEBUGGING
  - Since most users don't need the debugging on at all times, this helps reduce the default build size for UBL by over 2K, a little closer to fitting on 128K boards.

0e8242180d Chamber temperature monitoring and auto fan control.
This is an initial cut for feedback, updated for 2.0.x.

Chamber temperature is currently reported along with hot end and bed
temperatures to serial. The format is just like that used for hot end
and bed temperatures, but using 'C' prefix. As there is no heater,
target is always 0. Is this appropriate, is there a better way to report
chamber temperatures?

Chamber temperatures are not reported on the LCD in any way.

When auto chamber fan is enabled, it currently just uses the same
temperature threshold as the other auto controlled fans.

As the chamber temperature is not connected to any heater, it doesn't
undergo mintemp/maxtemp monitoring. This would need to change in the
future if chamber heating became a feature.

- Have `thermalManager` do watchdog reset before its ISR starts to prevent reset.
- Ensure that timers are stopped before reprogramming them to address tone issues.
- Improve SAM3XE reset when reflashed through the native port.

Cartesian UBL systems should not use SEGMENT_LEVELED_MOVES
There is significant downside to breaking up the long line segments on UBL Cartesian machines.   It adds a lot of extra computation but worse...  It cuts out all of UBL's off mesh Z-Height correction checks.    There have been a large number of people complaining about the nozzle going to infinity or crashing into the bed lately.   They are being caused by
```
void unified_bed_leveling::line_to_destination_cartesian()
```
not watching over the segments being queued up for movement.

Update UBL's Delta Probable locations
This is a non-intuitive change.   @oldmcg says in this post https://github.com/MarlinFirmware/Marlin/issues/7572#issuecomment-340641207 that using DELTA_PRINTABLE_RADIUS is better than DELTA_PROBABLE_RADIUS for setting the probe limits.   This is because the automatic probe code checks all locations for being reachable by the probe prior to doing the probe.

e0a6ee8da5 [2.0] Fix up G33, LPC1768 + SDCARD_SORT_ALPHA (#8250)
* Update Conditionals_post.h

* Add a cast to round() to convert to a unsigned int

Add's a cast to round() so that it will compile properly. round() returns a float which must be cast to a integer for the following % operation. Use a unsigned int as a negative index to an array is wrong. Should never be more than 255 points allowing us to use a 8 bit cast.

* Update G33.cpp
