Robert Griesemer 6019a52d4d go/types, types2: better error message when using *interface instead of interface ...

- detect *interface case and report specific error
- replaced switch with sequence of if's for more clarity
- fixed isInterfacePtr: it applies to all interfaces, incl.
  type parameters
- reviewed/fixed all uses of isInterfacePtr
- adjusted error messages to be consistently of the format
  "type %s is pointer to interface, not interface"

Fixes #48312.
