Better support for MMU devices with filament cutter(e.g. ERCF v2 and any MMU with a cutter like Filametrix) (#6241)

Browse Source 
flush_length variable is now provide correct value based on the flush
matrix set by the user.

pesudo code in Change filament gcode:
```
...
T1 

; Park head to the purging location
G1 X0 Y-5 F12000

; Purge certain amount of filament into waste bin
G1 E[flush_length] F600

...


```

This PR is based on the WIP tool changer branch #6087

Fixes #4194 #5937 #5912
