Port "Extend sparse infill" from Prusa (#2134)

Browse source 
* Remove BambuLab's implementation of solid infill bridging enhancement
, will use Prusa's instead

* Port "Extend sparse infill" from Prusa

* Improve anchoring by shifting the lines half-spacing

* Add missing fill patterns

* Improve anchoring by keeping fine details

* Make sure the opposite directions do not cancel each other
