Responding to #12383

XY probe offsets should be integers because adding decimal points makes the code larger. But if decimals are very much wanted, this commit removes the old restriction.

* Group status methods, share reset_status with Extensible UI
* Move common DOGM code to headers

* 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.

* Followup to LCD_TIMEOUT_TO_STATUS=0
* Make continuous purge screen fit 20x4
* Unify purge message modes
* Preserve last-set pause header mode
