CannotPreserveMemoization
We do need to fix the error location to point to the "callsite" rather
than the definition of the useMemo callback, but that aside, even if the
error message were perfect, it's not meant to be actionable to the user.
So let's change the severity to CannotPreserveMemoization. This
preserves the validation, but the eslint plugin won't report it.
