Robert Findley c8d4fe2adc go/types: temporarily pin the Checker to Interface during checking
While type checking expressions involving interface types, it is
possible that their type set is used before delayed actions are
processed. As a result, computeInterfaceTypeSet is called with a nil
checker, and errors in the interface type definition result in panics
(see #48234).

To avoid the panics, store a *Checker on Interface for use in between
checking of the interface type expression and processing of delayed
actions.

Fixes #48234
