Fix T84364: Sculpt symmetrize fails with shape keys

Use the BMesh symmetrize operator instead of using the modifier code.

While we could support shape-keys with the existing code used by the
mirror modifier, we'd need to add code-paths for evaluated mesh & bmesh
conversion to handle shape-keys differently just for this one case,
since we want to avoid copying & processing shape-keys layers for
evaluated meshes in general.
