Saves 128 bytes in testing with `mftest mega 1 -y`

A simple Z probe using a magnet to deploy a probe. See https://youtu.be/E7Ik9PbKPl0 for the sensor description...

Allow `ENABLED`, `DISABLED`, `PIN_EXISTS`, and `BUTTON_EXISTS` to take multiple arguments. Also add:
- Alias `ANY(...)` for `!DISABLED(...)`
- Alias `ANY_PIN(...)` for `PIN_EXISTS(a) || PIN_EXISTS(b) ...`
- Alias `EITHER(A,B)` for `ANY(...)`
- Alias `ALL(...)` and `BOTH(A,B)` for `ENABLED(...)`
- `NONE(...)` for `DISABLED(...)`

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.

* 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

As noted in #10777

=====================

add test to Travis

 - Add crc16 utility function
 - Implement CRC16 for config store, remove old checksum, increment layout version
 - Move UBL mesh store/load to MarlinSettings; increment UBL_VERSION
 - Begin to lay out MAT structure, prototype functions, etc.
 - Rename ubl.state.eeprom_storage_slot to .storage_slot
 - Misc. optimization
 - Cleanup/standardize/improve some messages

This is a work in progress!

The first character in the string wasn't blanked if the number went from >= 100 to <100, resulting in artefacts in the displayed string.

Also...   The memory corruption issue may be fixed.   The GCC compiler
was inlining static functions and this caused the G29() stack frame to
become much larger than the AVR could handle.
