PFW-1386 Use Marlin 2 unload sequence for single material 

The current unload sequence does not give good results.
The Marlin 2 sequence looks good on my end. This can be later
used to improve M600

Added all the constants from Marlin 2

* Advanced Pause for Filament Change
* - Adds the G-code M600 Filament Change to initiate a filament change.
* - This feature is required for the default FILAMENT_RUNOUT_SCRIPT.
*
* Requirements:
* - For Filament Change parking enable and configure NOZZLE_PARK_FEATURE.
* - For user interaction enable an LCD display, HOST_PROMPT_SUPPORT, or EMERGENCY_PARSER.
*
* Enable PARK_HEAD_ON_PAUSE to add the G-code M125 Pause and Park.
