Remove legacy value from IDEX menus and add post command option to M605

[InsanityAutomation]

First half of changes related to #17941

[Roxy-3D]

Is this going to work? The M605 S3 X200 was needed to get the extruders spaced properly....

[InsanityAutomation]

Just verified in the issues thread that it is applying the default correctly. The value persisted from the default assignment in motion.cpp from configuration_adv with no X arg ever assigned.
