  [clang][Interp] Add an EvaluationResult class (#71315)

Add an `EvaluationResult` class. This contains the result either as a
`Pointer` or as a `APValue`.

This way, we can inspect the result of the evaluation and diagnose
problems with it (e.g. uninitialized fields in global initializers or
pointers pointing to things they shouldn't point to).
