Subject: [GC] RefIsNull => RefIs. (#3516)

This internal refactoring prepares us for ref.is_func/data/i31, by renaming
the node and adding an "op" field. For now that field must always be "Null"
which means it is a ref.is_null.

This adjusts the C API to match the new IR shape. The high-level JS API
is unchanged.
