Initial port of organic tree support from PrusaSlicer (#1938)

Browse source 
* Initial port of organic tree support from PrusaSlicer

* Port missing Organic support parameters from PrusaSlicer

* Update parameter naming

* Reorganize the `raft_first_layer_expansion` and `raft_first_layer_density` parameters as they are not only used by rafts

* Reset support style only in simple mode

* Sync latest update from PrusaSlicer & copyrights

* Fix organic tree support crash with invalid parameters
