* 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.

In reference to #11000

- Move FWRETRACT to the planner
- Combine leveling, skew, etc. in a single modifier method
- Have kinematic and non-kinematic moves call one planner method

* Fix G29 (ABL) retry behavior

See https://github.com/MarlinFirmware/Marlin/issues/5597#issuecomment-397683325

Use macros that explicitly avoid double-evaluation and can be used for any datatype, replacing `min`, `max`, `abs`, `fabs`, `labs`, and `FABS`.

Addressing #10538

Fixes #10137

Some probes don't work near the edges of the bed. This change promotes MIN_PROBE_EDGE to a general setting that applies to all probing functions.

Some "fix-mounted" probes need manual stowing. And after probing some may prefer to raise or lower the nozzle. This restores an old option but tailors it to allow raise or lower as preferred.

* fix M48 for delta printers

fix M48 for delta printers. home printer if not already homed.

* remove ENABLED(DELTA)

remove ENABLED(DELTA) as it is not needed.

* Update M48.cpp

* abl needs queue.h

without queue.h abl will not compile since there is a script that runs at the end of it and we need to queue it up.
