It's shared by both 2D and 3D particles (+ CPU ones), so it makes sense to have as a common resource. It also allowed to disable compilation of Particles (3D) when using 'disable_3d'. Also cleaned up includes in SpatialEditorGizmos and some other places, as well as dropped dead code in material_editor_plugin.cpp.
