Adds `BindAlias` with a hybrid of `BindName` and `NameRef` semantics. I think it's slightly closer to `BindName` because it introduces a name, so I'm going more in that direction. This also matches the need for `bind_name_id` with imports on enclosing scopes. Note, only things that look like a name reference are being allowed on the RHS of `alias`. This includes builtins that look like name references, such as `bool`, but not ones that turn into values underneath, such as `false`.
