ConcentricGapFill pattern was used for internal narrow solid infill. Use arachne engine instead to remove gap fill inside the pattern and improve the extrusion path Signed-off-by: salt.wei <salt.wei@bambulab.com> Change-Id: I758d7c72eb71cc37026b7cebf746cc345014c3f5 (cherry picked from commit 0b6bacd21a091afc13d7b36a69e5b10f155bc6f8)
