[Feature] Add a new feature that allow user to insert extra solid infills (#10611)

Browse Source 
* refactor Infill rotation template

* clean up comments

* set default solid_infill_rotate_template to empty

* Fix an issue that infill_direction solid_infill_direction not working as expected

* Add Extra Solid Infill Feature
Introduced a new feature to insert extra solid infills at specific layers for enhanced strength in 3D prints.

* fix doc error

* fix image name

* support "#K" for Explicit Layer List

* update wiki
