Fix nullable field optionality in operations

Previously, a nullable Result field is generated as optional (marked by ? TypeScript modifier) by default. This is not correct, because generally at runtime such field can only be null, and not undefined (both missing from the object OR undefined). The only exceptions are when fields are deferred (using @defer directive) or marked as conditional (using @skip or @include).

Now, a nullable Result field cannot be optional unless the exceptions are met. This also limits avoidOptionals to only target Variables input, since some users may want to force explicit null when providing operation variables.
