[GC] Add struct.set (#3430)

Mostly straightforward after struct.get.

This renames the value field in struct.get to ref. I think this makes
more sense because struct.set has both a reference to a thing, and a
value to set onto that thing. So calling the former ref seems more
consistent, giving us ref, value. This mirrors load/store for example
where we use ptr, value, and ref is playing the role of ptr here
basically.
