Support material: When moving from one pillar to the other not need to retract (performance improvement) #5096

Is your feature request related to a problem? Please describe. Feature: a bit of print speed up: I noticed that when printing support material the standard rules for quality applies, as retract (which can be a slow operation), but support material volume don't need to be spark clean of filament from one pillar to the other, so retraction is useless while deposing support material.

Describe the solution you'd like Omit retraction when moving from one section to the other of the support material, it will be even useful

Describe alternatives you've considered There are not alternative other than don't mind missed opportunity for performance improvement

Additional context This can be optional, e.g. support_material_no_retract
