Subject: Restore the `extern` heap type (#4898)

The GC proposal has split `any` and `extern` back into two separate types, so
reintroduce `HeapType::ext` to represent `extern`. Before it was originally
removed in #4633, externref was a subtype of anyref, but now it is not. Now that
we have separate heaptype type hierarchies, make `HeapType::getLeastUpperBound`
fallible as well.
