    c: fix ICE with enum completed with packed attribute after forward decl
[PR116892]

    After forward declaration of an enum and when completing it with the
    attribute packed, we need to propagate TYPE_PACKED to all main variants.

            * c-decl.cc (finish_enum): Propagate TYPE_PACKED.
