Delay validation of receiver type as it may cause premature expansion of types the receiver type is dependent on. This was actually a TODO. While the diff looks large-ish, the actual change is small: all the receiver validation code has been moved inside the delayed function body, and a couple of comments have been adjusted. Fixes #51232. Fixes #51233.
