The reflect API normally grants only read-only access to non-exported fields, but it specially handles non-exported embedded fields so that users can still fully access promoted fields and methods. For example, if v.Field(i) refers to a non-exported embedded field, it would be limited to RO access. But if v.Field(i).Field(j) is an exported field, then the resulting Value will have full access. However, the way this was implemented allowed other operations to be interspersed between the Field calls, which could grant inappropriate access. Relatedly, Elem() is safe to use on pointer-embeddings, but it was also being allowed on embeddings of interface types. This is inappropriate because it could allow accessing methods of the dynamic value's complete method set, not just those that were promoted via the interface embedding. Fixes #22031. Fixes #22053.
