Various Emboss improvements from PS (#4039)

* Fix: invalid distance from surface when load from 3mf

Cherry-picked from prusa3d/PrusaSlicer@e1d9393e51

Co-authored-by: YFilip Sykala - NTB T15p <Filip.Sykala@Prusa3D.cz>

* Apply rotation angle given by style for new text object
Turn off feature 'use_surface' for new text object

Cherry-picked from prusa3d/PrusaSlicer@1cb156c815

Co-authored-by: YFilip Sykala - NTB T15p <Filip.Sykala@Prusa3D.cz>

* Store/Load align and per_glyph in Slicer.ini for text style

Cherry-picked from prusa3d/PrusaSlicer@fe16f5bdd1

Co-authored-by: YFilip Sykala - NTB T15p <Filip.Sykala@Prusa3D.cz>

* Store undo/redo snap after stop input-sliding

Cherry-picked from prusa3d/PrusaSlicer@fb4e4710e7

Co-authored-by: YFilip Sykala - NTB T15p <Filip.Sykala@Prusa3D.cz>

* Initialize SvgFile object in optional different way.

Cherry-picked from prusa3d/PrusaSlicer@0ff255eadc

Co-authored-by: YFilip Sykala - NTB T15p <Filip.Sykala@Prusa3D.cz>

* SPE-2103
Make snap-shot to undo/redo stack only on release slider

Connected with attributes:
Text/advanced(char gap, line gap, boldness, skew ratio)
SVG(size)

Also change range for Boldness. VRT font-Ascent.
(different font may have different slider value range)

Fix line gap (it was denied when per glyph was false)
