Hide cursor in sculpt mode
Based on yunisio suggestion https://blender.community/c/rightclickselect/Btdbbc/
When called from search it can hide cursor in Sculpt mode when mouse over View3d and bring it back over other areas.
If mouse get back to view3d cursor still appears - have no time to get it done.
Checkbox could be appended to VIEW3D_PT_tools_brush_display_custom_icon.draw().
