feat(graphql): add asyncDeepEquals to the graphqlClient

[Neelansh-ns]

Fixes / Enhancements

• Added asyncDeepEquals param to the GraphqlClient as the DeepCollectionEquality is an expensive operation and was running synchronously. This in turn would result in a jank whenever there is a response received and the equality check happens in the _cachedDataHasChangedFor function.
• To avoid the jank the developer can pass the async function for equality check, like compute() to move the operation to a different isolate.
• This also partially fixes Jank on every query #1196
