There's no reason for G28 to reset DUAL_NOZZLE_DUPLICATION_MODE, because it only affects the E stepper, unlike DUAL_X_CARRIAGE which affects the X steppers as well.

Some of the Rotations did not do the right thing with setting and clearing pixels.
I think it is correct now.   But if not...  It is much closer to being correct.

Make M2719 initialize the Max7219 registers and then run the initialization pattern (if one is specified).

* Add Multi Unit Support for Max7219 to bugfix_2.0.0

* Apply multi-MAX7219 to example configs

* Tweak some spacing, macros

When `INCH_MODE_SUPPORT` is enabled no default unit is set. This fixes it.

* Fix G29 (ABL) retry behavior

See https://github.com/MarlinFirmware/Marlin/issues/5597#issuecomment-397683325

The registers within the Max7219 can get corrupted a number of ways.  This allows the Max7219 to be reset and fully initialized.
And...  it also allows the user to see the initialization pattern.

Added reset bltouch instead. This ensure properly stow even when in error.

- Drop `max_jerk` with `JUNCTION_DEVIATION`
- Add `max_e_jerk_factor` for use by `LIN_ADVANCE`
- Recalculate `max_e_jerk_factor` when `junction_deviation_mm` changes
- Fix LCD editing of `junction_deviation_mm`
