Backport Draft Shield support from Prusa Slicer

[ucirello]

Is your feature request related to a problem? Please describe.
Up to BL X1/P1 series, there was no need for draft shields. However, OrcaSlicer support more printers than BambuStudio, and among them are open-frame printers.

Which printers will be beneficial to this feature
All ABS/ASA capable Artillerys, BIQUs, Comgrows, Voxelabs, and Flashforge Adventurer 5M, at least some of the RatRigs, all ABS/ASA capable Elegoo Neptunes, AnkerMake M5/C, All ABS/ASA capable Anycubics, etc.

Describe the solution you'd like
Back port the "Draft Shield" option from Prusaslicer - or at least, add a modifier to the skirt height definition that allows me to set the whole height automatically.

Describe alternatives you've considered
I can achieve the same behavior manually, but if I change layer height for instance, I have to re-slice, get that number, and manually feed into the form.
