Micha Reiser 2095ea8372 Add scope assertion to TypeInference.extend (#13764)
## Summary

This PR adds a debug assertion that asserts that `TypeInference::extend`
is only called on results that have the same scope.
This is critical because `expressions` uses `ScopedExpressionId` that
are local and merging expressions from different
scopes would lead to incorrect expression types.

We could consider storing `scope` only on `TypeInference` for debug
builds. Doing so has the advantage that the `TypeInference` type is
smaller of which we'll have many. However, a `ScopeId` is a `u32`... so
it shouldn't matter that much and it avoids storing the `scope` both on
`TypeInference` and `TypeInferenceBuilder`

## Test Plan

`cargo test`
