/**
* Retract or recover according to firmware settings
*
* This function handles retract/recover moves for G10 and G11,
* plus auto-retract moves sent from G0/G1 when E-only moves are done.
*
* To simplify the logic, doubled retract/recover moves are ignored.
*
* Note: Z lift is done transparently to the planner. Aborting
* a print between G10 and G11 may corrupt the Z position.
*
* Note: Auto-retract will apply the set Z hop in addition to any Z hop
* included in the G-code. Use M207 Z0 to to prevent double hop.
