Remove the builtin IR, and instead define builtin types locally. (#3910)

Browse Source 
We don't need it any more, and removing it simplifies a few things:

- One fewer predefined `File` and reserved ID.
- We now have simply `Builtin` instructions for builtins, instead of
having an `ImportRef` that indirectly references a `Builtin`.
- `ConstantId`s now always refer directly to a local constant, instead
of sometimes referring to an `ImportRef` for a constant in the builtins
IR.
