fix: enforce implicit invariants in EmitC stronger (#11381)
This PR fixes a bug where the closed term extraction does not respect
the implicit invariant of the
c emitter to have closed term decls first, other decls second, within an
SCC. This bug has not yet
been triggered in the wild but was unearthed during work on upcoming
modifications of the
specializer.
