[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`.

…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.

Updates to the latest version of the libs.

This change does not include Kotlin update to 1.5.30 due to following issues:
* Gradle Kotlin compile task presents a warning that Java compile task (we don't have any Java sources) uses different JVM target (Java version defaults to your local JVM default)
* Above warning can be fixed by explicitly configuring Java tasks (again we don't have any Java sources) to use Java 8 target OR through toolchain configuration - at least it should be, when using toolchain configuration `kapt` blows up with unable to find the toolchain JVM
* Android test project used as an integration test for Gradle plugin blows up with `Cannot have abstract method KotlinJavaToolchain.getJdk()`

* fix unit tests
`OptionalInput` is now supported for both kotlinx-serialization and Jackson. Updating test to account for this.
