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(...)`

・More ANALOG NUMBERING to Analog Input
・Add comment header to all the section of all the pins files

・Sort sections as follows:
1. Some special definitions (USBCON, LARGE_FLASH, etc)
2. Servos
3. Limit Switches
4. Z Probe
5. Steppers
6. Temperature Sensors
7. Heaters / Fans
8. Misc. Functions
9. LCD / Controller

・Move MAX6675_SS into "Temperature Sensors" section
・Adjust spacing

See #4316

Supports both dual and single head printers (with the correct config).
Includes community sourced feed rate fix.

Rename / move files.

Remove redundant definitions.

Includes:
  *firmware version / branch / date.
  *extruder count
  *board information (name, serial details, power supply type)
  *thermistors (names, min/max temperatures)
  *printer statistics (PRINTCOUNTER details)

Thanks to @thinkyhead for contributions.

Following up on #3231

For consistency with other pins, allowing use of `PIN_EXISTS` macro.

Apply `ENABLED` / `DISABLED` / `HAS_SERVOS` macros to pins files.

- Patched up for most included configurations

- K8200 uses a non-standard RAMPS with Z_ENABLE=63 ??
- Assuming from previous input that 3DRAG is the same.

There’s no need to ask users to uncomment Max Endstop pins when they
have them. These will be set to -1 later if the endstop option is
disabled.

Hopefully this is helpful to organization and future expansion….
