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(...)`

On a reset steppers were being initialized to incorrect direction. Original code wasn't respecting `INVERT_Z_DIR` define.

Fix a bug introduced in #9582

Initial manual Z move can be negative if your stepper is inverted. Leads to bad situations for crashed or initially booted printers.

- Added FILAMENT_RUNOUT_DISTANCE_MM option
- Added FILAMENT_MOTION_SENSOR option

* 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

When possible, make `active_extruder` a `constexpr` to save some PROGMEM.

- Allow planner to alter the deceleration phase of the currently executing block.
- Remove BUSY flag, as it is NON ATOMIC to set bits in the Stepper ISR and Planner at the same time.

...and recommended pulse width configuration for A4988

Always honor minimum period on stepper pulse generation, and fix timing calculations
