Add Align/Distribute objects on the print plate (#13373)

Browse Source 
* Add Align/Distribute objects on the print plate

Ports the Align/Distribute feature from BambuStudio 2.5 (AGPLv3,
same license as OrcaSlicer). Adds a new GLGizmoAlignment helper
that operates on the GLCanvas3D selection, twelve thin Plater
wrappers, and an Align/Distribute submenu attached to the same
five context menus BambuStudio attaches it to: object menu, text
part, BBL part, and the single/multi-volume context menus.

GLCanvas3D::do_move gains a defaulted force_volume_move parameter
so the helper can move multiple selected volumes within a single
object even when selection mode is Instance. GLGizmosManager gains
check_object_located_outside_plate, which switches the active plate
to the one containing the selection before align/distribute runs.
