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.

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

gcc/testsuite/ChangeLog:
* gcc.dg/pr116892.c: New test.
