[generator] add IDValueUnboxer for correctly serializing ID value cla…

…ss (ExpediaGroup#1385)

Since `ID` is a value class, it may be represented at runtime as a wrapper or directly as underlying type. Due to the generic
nature of the query processing logic we *always* end up with up a wrapper type when resolving the field value. As a result,
in order to ensure that underlying scalar value is correctly serialized, we need to explicitly unwrap it by registering
`IDValueUnboxer` with your GraphQL instance.

```kotlin
// registering custom value unboxer
val graphQL = GraphQL.newGraphQL(graphQLSchema)
    .valueUnboxer(IDValueUnboxer())
    .build()
```

`IDValueUnboxer` is automatically registered by `graphql-kotlin-spring-server`.

[generator] add runtime warning on deprecated context usage (ExpediaG…

…roup#1323)

### 📝 Description
This PR updates `FunctionDataFetcher` so that it logs a warning when injecting a `GraphQLContext`.  This functionality is [deprecated](https://github.com/ExpediaGroup/graphql-kotlin/blob/master/website/docs/schema-generator/execution/contextual-data.md#interface-injection-deprecated).  Unlike the `GraphQLContext` interface itself, which is annotated `@deprecated, there is no compile or runtime time warning when using `GraphQLContext` interface injection in a query or mutation.
