According to #123 negative values for XY at or below -100 are displaying incorrectly, dropping the first digit. Deltas can easily have XY values in this range. This PR adds a function to display floats/ints formatted like `_123`, `-123`, `_-12`, or `__-1` as appropriate and applies it to the XY coordinates on Hitachi displays. It also moves the Z value to the right to be consistent with the XY formatting.

Keep "astyled" reformatting

Centred the logo for 16x4 and 20 x4.
Moved version to the bottom line
Code shrink to 704 bytes.

Uses about 488 byte of progmem and 32 byte of RAM.
For that configurable.

Apply `ENABLED` / `DISABLED` macros to LCD-related files.

Also clean up some trailing spaces in a few other sources

- Also show 2 digits past decimal for Z on DOGM

to avoid errors in Marlin_main.cpp. #1860

In the include tree of Marlin_main.cpp the decision between the display types is not made.
To include the right LCD_STR_* ether 'dogm_lcd_implementation.h' or 'ultralcd_implementation_hitachi_HD44780.h' with all their code.
A 'dogm_lcd_implementation.h.h' would be a curiosity.
So i moved both of the definition blocks to conditionals.h

On the long term it could make sense to use the same numbering for the u8glib and the hitachi symbols.

This rolls back to commit 06f767d608.

- Some messages should not expire with `PROGRESS_MSG_EXPIRE`.
- Simplify conditional for progress bar with sanity checks.
- Rename `messageTick` to `expireStatusMillis` and make it the expire
time.

and make use of column 20.

In the new method we pass the character that should be used for
selected state, not the character to print always.

in ultralcd_implementation_hitachi_HD44780.h lcd_print( about array index.

- Get rid of _selected functions, passing selected state instead

- Add BIT and TEST macros
- Add _APPLY_ macros to stepper.cpp to help with consolidation
- Consolidate code in stepper.cpp using macros
- Apply standards in stepper.cpp
- Use >= 0 instead of > -1 as a better semantic
- Replace DUAL_Y_CARRIAGE with Y_DUAL_STEPPER_DRIVERS

Top -> down:
We don't need LiquidCrystalRus.cpp and LiquidCrystalRus.h any more. Functionality is now in utf_mapper.h
Comment on LCD_STR_BEDTEMP about behaviour in strings.
Change LCD_STR_ARROW_RIGHT from "\x7E" to ">" because "\x7E" is only ARROW_RIGHT on displays with DISPLAY_CHARSET_HD44780_JAPAN.
Introduce the counting UTF8 enabled lcd_print functions.
Replace the old lcd.print functions and make use of them.
A bit of reformatting around the changes.

The encrot values are used in only one place, and don’t vary, so remove
redundant references.

Introduced lcd_strlen() and lcd_strlen_P().
Replaced the old functions where necessary.
Reworked language_ru.h.

Speeded up test for zero length string in cardreader.cpp

- Also partial cleanup of Marlin_main.cpp with a smidgen of Doxygen.

sp=space-padded, similar to: ns=no-sign

No matter what LANGUAGE_CHOICE was set to it would always take the en branch.
I revamped it a bit to use a macro to create the language include file name. This required a slight tweak to the RU declaration since it's special-cased in a couple places in code.

This is an attempt to pull my changes from #1222 over.

Tested for SAV MKI and SAV 3D LCD on lewihe.

sp=space-padded, similar to: ns=no-sign

Breaking up languages.h makes it easier to translate. Using language
codes makes it easier to select a language and sets the naming standard.
