Added EVENT_GCODE_PARK_Tx

[Dakkaron]

Description

Added EVENT_GCODE_PARK_Tx as described in #25181.

These gcodes will be run before the pre-existing EVENT_GCODE_TOOLCHANGE_Tx gcode commands.

The main difference is that EVENT_GCODE_PARK_Tx is selected based on the extruder that was in use before the tool change command, while EVENT_GCODE_TOOLCHANGE_Tx is selected based on the new extruder.

This allows the user to specify a parking gcode and a pickup gcode.

So for example say tool 2 is currently active and the user issues the command T3.

This will run the following commands:

1. EVENT_GCODE_PARK_T2
2. EVENT_GCODE_TOOLCHANGE_T3

Requirements

• Only relevant for printers with tool changers that are currently not covered by the pre-defined tool changer variants. For example, tool changers that use servos to move tools in place and lock them there.

Benefits

Can be used as a fall-back for all types of tool changers that are currently not covered by the pre-defined tool changer variants. Any tool changer that can be controlled by gcode commands can be configured using this change.
