All ExtUI LCDs need to keep up with ExtUI API changes.

Arduino doesn't (always) support `float` formatting in strings. So either cast to `int` or use `dtostrf()` to fix these usages.

…And save backlash, fil. sensor, ExtUI userdata to EEPROM.

* Make CardReader a static class
* Make CardReader flags into bitfields

* 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.

- Remove `print_job_timer.stop()` from `disable_all_heaters`
- Call `print_job_timer.stop()` for relevant `disable_all_heaters()`.
- Split up `kill()` for watchdog interrupt safety
