Fix 3MF import crash for silent-mode machine limits with legacy vector sizes (#12289)

Normalize printer_options_with_variant_2 (stride=2) machine limit vectors during preset merge to handle legacy 3MF/projects that store only a single (normal,silent) pair despite multiple printer variants, preventing set_with_restore() size-mismatch crashes.

Crash error message during 3MF import as project:

3MF attached that causes the bug.
