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.

* Move special characters to language.h
* Apply some naming standards
* Clean up menu item draw functions
* Rename some Temperature methods
* UI => ExtUI

In reference to #11000

* Apply #pragma once in headers
* Adjust some thermistors formatting
* Misc cleanup and formatting

- 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

* Fix Z value display
* Add HAS_PRINT_PROGRESS
* Alternative Info Screen option
* Add LCD_INFO_SCREEN_STYLE to example configs

- Add methods to access print counter data
- Clean up some inconsistent method names
- Clear lcd status after filament change
- Implement `lcd_reset_status` so it works like UltraLCD

* Clean up Temperature PID
* Improve EEPROM read/write/validate
* Group `SINGLENOZZLE` saved settings
* Group planner saved settings
* Group filament change saved settings
* Group skew saved settings
* Group `FWRETRACT` saved settings

With default config and `EEPROM_SETTINGS`, saves over 200 bytes of PROGMEM.

* Modify method to utilize live adjustment of hotend z offset

Should probably move config option to babystepping and rename as it may now apply to all multiextruder systems

* Move config item and catchup other code to current method
