  [WGSL] Add reference types

Reviewed by Myles C. Maxfield.

Remove the existing `TypeReference` node, which was a workaround to have a node
that points to another type node, but it's now no longer necessary.

Replace it with a `ReferenceType` node. The similar name is a bit confusing,
but this actually refers to a reference to type, i.e. `T&` in source.

The node still isn't used in this patch, but another patch will follow this one.
