Rename anyref to externref to match proposal change (#2900)

anyref future semantics were changed to only represent opaque host values, and thus renamed to externref.

[Chromium](https://bugs.chromium.org/p/v8/issues/detail?id=7748#c360) was just updated to today (not yet released). I couldn't find a Mozilla bugzilla ticket mentioning externref so I don't immediately know if they've updated yet.
