Retire the untuned re3D umbrella presets superseded by the nozzle variants

"Update re:3D profiles" (#13750) added the tuned "@0.4/@0.8 nozzle" and
"@0.8/@1.75 nozzle" variants but kept the five original un-suffixed presets,
trimming each to a stub that overrides only filament_vendor while still
claiming every printer of both nozzles. On any re3D printer the stub was
selectable alongside the ~50-key variant that actually tunes the material,
which is what forced five filament_id salt splits to keep the pair apart.

Drop the stubs. The variants already carry the products' ids, so nothing is
re-minted; renamed_from redirects each retired name to the smaller-nozzle
variant, and "re3D rPETG @0.8 nozzle" additionally takes over the
"re3D Greengate rPETG" mapping that lived on the deleted umbrella. Each
printer model's default_materials now lists the variants for its own
nozzles rather than the stub.
