Compute Planar Section -> Split Surfaces loses vertex & face attributes on newly generated mesh layers (v2023.12)

[fseegraeber]

Reproduction steps:

• Load a mesh
• Make sure it has texture/color/or any other per face/vertex attributes
• Filters -> Quality Measures... -> Compute Planar Section
  • enable "create also split surfaces" and set "plane reference: bounding box center"
• The newly generated mesh layers *_over and *_under lose all face/vertex attributes, such as texture uvs, color or custom attributes

I had a quick glance at the code. To me it looks like per wedge tex coordinates are handled, so I'm not sure what's going on. But I could be wrong on this also.
