Replace Z_RAISE_BEFORE_HOMING with MIN_Z_HEIGHT_FOR_HOMING
This was made as a fix for#3001. jbrazio was faster.
Nerveless i'll take the chance to simplify z-raising in G28 a bit.
Make raising z work when AUTO_BED_LEVELING_FEATURE is disabled.
Raise for homing every axis, but only once and only if not already high enough.
Clean out some extra complications when Z_SAFE_HOMING is defined.
