Add a rewriter that reifies implicit conversions into a call to the `__convert` intrinsic. Code generators can recognize this intrinsic and use it to generate appropriate conversion code. Part of this work involves redesigning the type annotations system. Annotations are now only applicable to opaque and object types. Instead of inspecting annotations directly, code generators should use `hcl2.GetSchemaForType` to extract the `schema.Type` for a `model.Type`.
