Arduino doesn't (always) support `float` formatting in strings. So either cast to `int` or use `dtostrf()` to fix these usages.

- Use the return value from probe_pt during `G34`
  Eliminate the assumption that probe_pt leaves current_position set to values relative to the probed points. This is not always true, depending on the raise_after argument.
- Add '`E`' argument to `G34` command allowing stowing between each probe.

queue.buffer is in bss area, start_free_memory starts from heap then above of bss

…And save backlash, fil. sensor, ExtUI userdata to EEPROM.

Add option to move away from endstop after homing.
- Add `ENDSTOP_BACKOFF` for printers with a recessed Z home button (Lulzbot TAZ 6).
- Also prevents chattering when sensorless homing with axes against bumpers.

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(...)`
