Due to recent spec changes, this CL removes the type immediate of
ref.is_null again. Instead we check if the type of the input parameter
is nullable.

As per the latest update to the 'reference types' wasm proposal, the
nullref type is removed. Following that, all its uses in V8 were also
removed. This CL:
- Removes now dead code referencing nullref.
- Changes names of functions/exceptions containing 'nullref' to 'null'.
- Changes nullref to the corresponding nullable type in some tests.

The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.
